Q.2 There are two containers on a table. A and B. A is half full of wine, while B, which is twice A's size, is one-quarter full of wine. Both containers are filled with water and the contents are poured into a third container C. What portion of container C's mixture is wine? 

• 33.33%
• 58.33%
• 69.33%
• 47.33%
• None of the above

Solution: -A

Let the size of container A is "x"
then B's size will be "2x"
A is half full of wine ⇒x2
So remaining "x2 " of A contains water B is a quarter full of win
⇒2x4
⇒x2
So remaining ⇒2x–x2=3x2
So 3x2 of B contains water.
Totally C has A's content + B's Content
= x + 2x = 3x
Wine portion in C = x2 of "A" + x2 of
"B" x portion of wine Water portion in C
= x2 of "A" + 3x2 of "B"
⇒4x2
⇒2x portion of water
So portion of wine in C is
x3x=13 portion of wine
if 1/3 expressed in % 13×100 = 33.33%
Ans : 33.33% of wine.

Q 3. An article was bought for Rs. 3000 and it should be sold at a profit of Rs. 300, what should be the selling price of that article. 

• 3200
• 3400
• 3500
• 3300
• None of these

Solution:-D

Cost price = 3000, Profit = Rs. 300
We know that
Profit = S.P – C.P
=> S.P = Profit + C.P
= 300 + 3000
= 3300.

Q4.The marked price of a radio is 30% more than its cost price. If a discount of 10% is given on the marked price, find the gain percent.

• 20%
• 17%
• 19%
• 21%
• None of the above

Solution:-B

Given
Let Cost Price = 100 Rs
Marked price = 30 % more than Cost Price
= 30 % of C.P + C.P
= ( ( 30 / 100 ) x 100 ) + 100
= 30 + 100
= 130 Rs
Given Discount = 10 % of marked price
= ( 10 / 100 ) x 130
= 13 Rs
Selling Price = Marked Price - Discount
= 130 - 13

Q 5.The HCF of two numbers is 24. The number which can be their LCM is

• 84
• 128
• 120
• 274

Solution:-D

Let the two numbers be x and y ,

HCF = 24

LCM = 1344

HCF × LCM = x×y

24×1344 = xy

xy = 32256

(x-y) = 80

x = 80+y

(80+y)×y = 32256

y^2 +80y -32256 = 0

y^2 +224y -144y -32256 = 0

y(y+224) -144(y+224) =0

y = 114 & -224

x = 80+114

x = 194

x+y = 194+80

= 274

Q 6. Salaries of Robert and Sam are in the ratio 2 : 3. If the salary of each is increased by Rs. 4000, the new ratio becomes 40 : 57. What is Sam's present salary?

• 36000
• 34000
• 39000
• 38000
• None of these

Solution:-D

Let the original salary of Robert and Sam be 2k and 3k respectively. Then (2k+4000)/(3k+4000)=40/57 => 57(2k+4000) = 40(3k+4000) => 114k + 2,28,000 = 120k + 1,60,000 => 68000 = 6k => 3k = 34000
Sam's present salary = 3k+4000 = 34000 + 4000 = 38000

Q7.A person receives a sum of Rs. 2100 as interest for investing some amount at 10% p.a compounding annually for 2 years. Find the amount invested at the beginning?

• 9000
• 10000
• 9500
• 10500

Solution:-B

Given Compound Interest = Rs.2100
Rate of Interest ( r ) = 10 % p.a
No.of years ( n ) = 2
To find , amount received at the beginning => principal
Compound Interest = P [ 1 + ( r / 100 )ⁿ- 1 ]
=> 2100 = P[ 1 + ( 10 / 100 )²- 1 ]
=> 2100 = P[ 1 + ( 1 / 10 )²- 1 ]
=> 2100 = P[ ( 11 / 10 )²- 1 ]
=> 2100 = P[ ( 121 / 100 ) - 1 ]
=> 2100 = P[ 21 / 100 ]
=> 2100 x ( 100 / 21 ) = P
Principal = Rs. 10000
Amount invested at the beginning = Rs. 10000

Q 8. Vijay requires 40 % to pass. If he gets 185 marks, falls short by 15 marks, what was the maximum marks he could have got?  

• 500
• 450
• 600
• 400

Solution:- A

Given, Pass percentage = 40%
Pass mark = 185 + 15 = 200

Let the maximum marks (100%) be x
Then, 40% of x = 200
=> (40/100) * x = 200
=> (4/10) * x = 200
=> x = (200 * 10) / 4
=> x = 500
Therefore, the maximum marks = 500

Q 8.There were 45 students in a hostel, if the number of students increased by 7, the expenses of the mess were increased by Rs. 39 per day while the average expenditure per head diminished by Re.1. What is the original expenditure of the mess (in Rs)?

• 562
• 585
• 650
• 480

Solution:-B
Number of students = 45
Increased Number of students = 45 + 7 = 52
Increased Expense = Rs.39
Average expenditure decreased by = Re. 1Let the original expenditure be Rs.x
Original average expenditure = X/45
New average expenditure = (x+39)/52

So by, Average expenditure decreased by = Re. 1
=> Original average expenditure - New average expenditure = 1
=> (x/45) - ((x+39) / 52) = 1
=> [52x - 45((x+39)] / [45*52] = 1
=> [52x - 45x - 1755] / 2340 = 1
=> 7x - 1755 = 2340
=> 7x = 2340 – 1755
=> 7x = 4095
=> x = 585
so, original expenditure is Rs 585

• 35
• 32
• 33
• 24

Solution:-c

Let the numbers be 3x and 5x
Then (3x-9)/(5x-9) = 12/23
=> 23(3x-9) = 12(5x-9)
=> 69x - 207 = 60x - 108
=> 69x - 60x = 207 - 108
=> 9x = 99
=> x = 11
Therefore the smaller number is 3x = 3 x 11 = 33
Answer is 33

Q 10.Two trains are running in opposite directions in the same speed. The length of each train is $120$ metre. If they cross each other in $12$ seconds, the speed of each train (in km/hr) is

• 42
• 36
• 28
• 30

Solution-B

Distance covered $=(120+120)=240\text{metre}$

Time $=12$ seconds

Relative speed $=\frac{\mathrm{240/}}{12}=20\text{m/s}$
$=20\times \frac{\mathrm{18/}}{5}=72\text{km/hr}$

Relative speed in this case is the sum of the speeds of the trains and each train has same speed, speed of each train
$=\frac{\mathrm{72/}}{2}=36\text{km/hr}$

The yearly festival was close at hand. The store room was packed with silk fabrics. Gold ornaments, clay bowls full of sweet curd and platefuls of sweetmeats. The orders had been placed with shops well in advance. The mother was sending out gifts to everyone.

The eldest son, a government servant, lived with his wife and children in far off lands. The second son had left home at an early age. As a merchant he travelled all over the world. The other sons had split up over petty squabbles, and they now lived in homes of their own. The relatives were spread all across the world. They rarely visited. The youngest son, left in the company of a servant, was soon bored and stood at the door all day long, waiting and watching. His mother, thrilled and excited, loaded the presents on trays and plates, covered them with colourful kerchiefs, and sent them off with maids and servants. The neighbours looked on.

The day came to an end. All the presents had been sent off.

The child came back into the house and dejectedly said to his mother, “Maa, you gave a present to everyone, but you didn’t give me anything !” 

His mother laughed, “I have given all the gifts away to everyone, now see what’s left for you.” She kissed him on the forehead.

The child said in a tearful voice, “Don’t I get a gift ?”

“You’ll get it when you go far away.”

“But when I am close to you, don’t I get something from your own hands ?”

His mother reached out her arms and drew him to her. “This is all I have in my own hands. It is the most precious of all.”
