**Answer:** 85

The average marks of 3 students A, B and C is 60. When another student D joins the group, the new average becomes 56 marks. If another student E, who has 3 marks more than D, joins the group, the average of the 4 students B, C, D and E becomes 55 marks. How many marks did A get in the exam?

a. 50 | b. 54 |

c. 51 | d. 53 |

Answer: c

Explanation:

Given that A + B + C = 60 × 3 = 180

A + B + C + D = 56 × 4 = 224

Therefore, D = 44

E = 44 + 3 = 47

Given, B + C + D + E = 55 × 4 = 220

B + C + 44 + 47 = 220

⇒ B + C = 220 – 91 = 129

So A + 129 = 180 ⇒ A = 51

Curious Elva asked her father what he would gift for her nineteenth birthday. Father replied that it would depend on the day of the week and be one of SUNglasses, MONeybag, …, FRIedcake, and SATchel. Please help Elva find the day of the week on 08-Jan-2029

a. Monday | b. Tuesday |

c. Thursday | d. Saturday |

Answer: a

Explanation:

Number of odd days upto 2000 = 0

From 2001 to 2028 = 28 + 7 = 35 = 0 ( ∵

“>∵∵

35/7 remainder zero)

From 2019 January 1 to 7 = 7 = 0

So 08 – Jan – 2029 falls on the same week day as 1-1-1 which is Monday.

In the simple subtraction problem below some single digits are replaced by letters .Fined the value of 7A+5D+6CD?

A5C5

-1B87

———-

674D

Sol: 15 – 7 = 8 So D = 8

10 + (C -1) – 8 = 4 So C = 3

10 + (5-1) – B = 7 So B = 7

(A-1) – 1 = 6 So A = 8

7A + 5D + 6CD = 56 + 40 + 144 = 240

Star question:

If f(1)=4 and f(x+y)=f(x)+f(y)+7xy+4,then f(2)+f(5)=?

Sol: Let x =1 and y = 1

f(1 + 1) = f(1) + f(1) + 7 x 1 x 1 + 4 ⇒

“>⇒⇒

f(2) = 19

Let x =2 and y = 2

f(2 + 2) = 19 + 19 + 7 x 2 x 2 + 4 ⇒

“>⇒⇒

f(4) = 70

Let x = 1 and y = 4

f( 1 + 4) = 4 + 70 + 28 + 4 = 106

f(2) + f(5) = 125

How many two digit numbers are there which when subtracted from the number formed by reversing it’s digits as well as when added to the number formed by reversing its digits, result in a perfect square.

Let the number xy = 10x + y

Given that, 10x+y – (10y – x) = 9(x-y) is a perfect square

So x-y can be 1, 4, 9. ——– (1)

So given that 10x+y +(10y +x) = 11(x+y) is a perfect square.

So x+y be 11. Possible options are (9,2), (8,3),(7,4),(6,5) ———(2)

From the above two conditions only (6,5) satisfies the condition

Only 1 number 56 satisfies.

Two cars start from the same point at the same time towards the same destination which is 420 km away. The first and second car travel at respective speeds of 60 kmph and 90 kmph. After travelling for sometime the speeds of the two cars get interchanged. Finally the second car reaches the destination one hour earlier than the first. Find the time after which the speeds get interchanged?

Let the total time taken by the cars be a and b

Let the time after which the speed is interchanged be t

For car A, 60t+90(a-t) = 420, 90a – 30t = 420 …….(1)

For car B, 90t + 60(b-t) = 420, 60b + 30t = 420 ….(2)

Using both (1) and (2), we get 90a + 60b = 840

But as a – b =1, 90a + 60(a-1) = 840.

Solving a = 6.

Substituting in equation 1, we get t = 4

A necklace is made by stringing N individual beads together in the repeating pattern red bead, green bead, white bead, blue bead and yellow bead. If the necklace begins with a red bead and ends with a white bead, then N could be:

Ans: The pattern is R G W B Y R G W B Y R …….

So, White bead comes at these positions 3rd, 8th, 13th, 18th…

If we take this as a arithmetic progression, then this series can be expressed as 3 + (n – 1) 5. ( From the formula for general term of AP = a + (n-1)d).

This can be expressed as 5n – 2

We check the answer options so only 68 satisfy the condition.

A sheet of paper has statements numbered from 1 to 40. For all values of n from 1 to 40, statement n says: ‘Exactly n of the statements on this sheet are false.’ Which statements are true and which are false?

a) The even numbered statements are true and the odd numbered statements are false.

b) The odd numbered statements are true and the even numbered statements are false.

c) All the statements are false.

d) The 39th statement is true and the rest are false

Ans: Assume there is only one statement is there. The statement should read “Exactly 1 statement on this sheet is false” . If the truth value of the statement is true, then given statement should be false. This is contradiction. If the statement is false, Then the given statement is true. but there is not other true statement.

Assume there are two statements. By the above logic, 2nd statement should not be true. But 1st statement is true as it truthfully says the truthfulness. By this logic we know that If there are “n” statements, (n-1)th statement is the only true statement And all other are false

10 suspects are rounded by the police and questioned about a bank robbery. Only one of them is guilty. The suspects are made to stand in a line and each person declares that the person next to him on his right is guilty. The rightmost person is not questioned. Which of the following possibilities are true?

A. All suspects are lying.

B. leftmost suspect is innocent.

C. leftmost suspect is guilty

a) A only

b) A or C

c) A or B

d) B only

There are only 2 cases. Either left one is guilty or one of the remaining 9 to his right is guilty.

So If the left most is guilty, All the statements including the guilty one are lies. A and C are correct.

Or If Any one except left most one is guilty, Then one of the statements given by the person should be true. In this case all the suspects are lying does not hold. So If B is correct, A is not correct. i.e., only A or B is correct. Option C is correct.

Kate wanted to buy 2kgs of apples. The vendor kept the 2kg weight on the right side and weighed 4 apples for that. She doubted on the correctness of the balance and placed 2 kg weight on the left side and she could weight 14 apples for 2 kgs. If the balance was correct how many apples she would have got?

As she got less apples when the weight put on the right side, the left pan has more weight say w kgs.

Now w + 4a = 2

and w+ 2 = 14a

Solving we get a = 2/9 Kgs.

So she gets, 2/(2/9) = 9 apples

- Type of Interview: Off Campus TCS Ninja Interview TNSLPP

**Student Interview**

I got placed in the TCS Ninja in February 2018. I had attended the TCS Ninja OFF CAMPUS placement drive through TNSLPP.

TNSLPP is basically an mass pool off campus drive for various companies like TCS, TCS Ninja CTS, Wipro, HCL etc.

The TCS Ninja recruitment took place in two rounds. The first round was the online test section which had the Verbal Ability section, quantitative test, coding test and the programming concepts test. The second round was the interview.

Most of my preparations for TCS Ninja was based on study materials provided by my college and PrepInsta. I came across this website when I was looking for TCS Ninja sample papers and interview experiences over the net. The website provided all the information and help I needed. I also found TCS Ninja questions for both the written round and the interview round.

My first round was scheduled for me on January 31, 2018.

**Round 1: ****The Online Test Section**

**Verbal Ability –** Cloze test was conducted in this section. Here a passage was given with some blanks and I had to fill answers using the options provided in the drop-down menu of each blank. This section had negative marking also.

**Quantitative Ability –** This test had some questions from quantitative aptitude and reasoning. There were 30 aptitude questions. The best part was, the study materials present at the PrepInsta website helped me a lot to get through this round.

**Coding Section –** The coding test had some coding questions. These questions contained negative marking. I did pretty well in this section.

**Programming Concepts Section –** This section was comprised of some programming questions that were easy for me to answer.

After the written test, some days later, I got my result on February 2, 2018, and was called for the Face to Face interview. The call letter mentioned the interview venue at Chennai TCS Ninja branch on 9th February 2018.

I reached the assigned venue and on the allocated time. Although I was quite nervous about the interview, I went for it with confidence. As my first round went well due to PrepInsta, even this time I prepared myself with some interview questions given on their website.

**Round 2: Interview**

The interview was taken by a panel of three people. These people were from Human Resource, Technical Resource, and a Manager. All of themwere sitting in the interview hall.The interview was not too long, and he asked me some simple questions.

**Managerial Interview**

Some of the questions asked by the manager were:

One of the technical team members was also seated on the panel. He tested me on my technical skills. He asked me some simple technical questions about programming concepts and basic concepts of OOPS, C, and C++.

** HR Interview**

The HR asked me some questions towards the end. Some of them were:

The interview went pretty well and was over soon. The panel told me that I would get results through email. Ten days after my face-to-face interview, I received an email from TCS saying that I got selected for the job. The email contained my offer letter for the job. I accepted the offer the same day.
