Let the speed of the bike be x kmph.

Then, speed of the bus = 

(140/100)x  =  (7/5)x kmph

∴70/x- 70/(7/5)x = 12/60

70/x - 50/x = 1/5

x = (20 x 5)/1 = 100 kmph

1 woman 1 day's work = 1/192

1 man 1 day’s work = 1/96

Work done in 3 days = 1/96 x 16 x 3 = ½

Remaining work = 1 - \frac{1}{2} = \frac{1}{2} 

(6 man + 4 woman)'s 1 day's work = (6/96 + 4/192) = 1/12 

1/12 work is done by them in 1 day.

½ work is done by them (12 x \frac{1}{2} = 6 days.

Time from 7 a.m. to 4.15 p.m. = 9 hrs 15 min. = 37/4 hrs.

3 min. 5 sec. of this clock = 3 min. of the correct clock.

37/720 hrs of this clock = 1/20 hrs of the correct clock

37/4 hrs of this clock =  \frac{1}{20}\times \frac{720}{37}\times \frac{37}{4} hrs of the correct clock

  = 9 hrs of the correct clock

Hence, The correct time is 9 hrs after 7 am, i.e. 4 pm

In order that two books on History are never together, we must place all these books as under:

X E X E X E X ... X E X

where E denotes the position of an Economics book and X that of a History book. 

Since there are 21 books on Economics, the number of places marked X are therefore, 22

Now, 19 places out of 22 can be chosen in ^{22}C_{19} = ^{22}C_{3} = (22 x 21 x 20) / (3x 2 x 1) = 1540 ways.

Hence, the required number of ways 1540.

As per question,

Let the maximum possible marks = X

Difference between marks of Manish and Anjali = 23+34

(64% – 52% )of X = 57

12% of X = 57

So marks obtained by Katrina = 84% of X = 7*57 = 399

Let A, B, C be the respective events of solving the problem and A’, B’, C’ be the respective events of not solving the problem. 

Then A, B, C are independent event

Now,  P(A) = \frac{1}{2} , P(B) = \frac{1}{3} and P(C)=\frac{1}{4}

P(A’) = \frac{1}{2} , P(B’) = \frac{2}{3} , P(C’) = \frac{3}{4}  

∴ P( none  solves the problem) = P(not A) and (not B) and (not C)  

= P(A’∩B’∩C’)

=P(A’)P(B’)P(C’)

 [∵ A, B, C are Independent]

= \frac{1}{2}\times \frac{2}{3}\times \frac{3}{4}

= \frac{1}{4}

Hence, P(the problem will be solved) = 1 - P(none solves the problem) 

= 1 - \frac{1}{4}

= \frac{3}{4}

Given, 4^{362} + 6^{52672} + 348^{836} + 24^{11} + 1

Power Cycle of

4 is 4, 6 

6 is 6 

8 is 8, 4, 2, 6

1 is 1

4^{362}- 362 is even number , So the unit digit value is 6 

6^{52672} - It is always 6

348^{836}-  836/4 the remainder is 2 , So the second value is 4

24^{11}- 11 is odd number, So the unit digit value is 4

1 - It is always 1 

Total = 21

Therefore, The unit digit is 1

The number of liters in each can = HCF of 80, 144 and 368 = 16 liters.

Number of cans of Frooti = \frac{368}{16} = 23

Number of cans of Coke = \frac{80}{16} = 5

Number of cans of Fanta = \frac{144}{16} = 9

The total number of cans required = 23 + 5 + 9 = 37 cans.

Let Bhuvan’s weight be X kg.

According to Bhuvan, 66 < X < 73.

According to Ashish, 60 < X < 70.

According to Deepika, X < 69.

The values satisfying all the above conditions are 67 and 68.

Required average = (67 + 68) / 2 = 67.5 kg

Given total rupees = 20 Rs

No. of one rupee stamps = 3

Now, remaining money = Rs. 17

With that he buys only 2 and 5 rupee stamps

Let number of Rs. 5 stamps = a

Let number of Rs. 2 stamps = b

5a + 2b = 17

a = 3, b = 1 (possible)

b = 6, a = 1 (possible)

=> But given that they are different in number so, a is not equal to 3

one rupee stamps = 3

2 two stamps = 6

5 rupee stamps = 1

Total number of stamps = 10.

A is a male and married to B. So, A is the husband and B is the wife.

C is the brother of A.

D is the son of C.

E, who is the sister of D, will be the daughter of C.

B is the daughter-in-law of F whose husband has died means F is the mother of A. 

A is a male. 

B, the wife is female. 

C, the brother is male. 

D, the son is male. 

E the sister is female. 

F, the mother is a female. 

So, there are a total of 3 males.

The following seating arrangement is extracted from the given information:

The second letter in the series L decreases by one.

The fourth letter switches from A to Z and back A alternatively.

The first and third letters consist of an alphabetical order beginning with the letter E and spaced by 2 letters.

Meaningfully relating all the words in a sequence,

Population,          Unemployment,         Penury,         Malady,          Death

1                                   5                            2                     4                      3

Here, the following two series are going on:

7 \times 2 + 1 = 15,</span>           <span style="font-weight: 400">7 \times 3 + 2 = 23,           </span> <span style="font-weight: 400">7 \times 4 + 3 = 31

10 \times 2 + 2 = 22,       </span> <span style="font-weight: 400">10 \times 3 + 3 = 33,         </span> <span style="font-weight: 400">10 \times 4 + 4 = 44

Following the above sequence, the next number should be 31.

But here in the sentence, one is in possessive pronoun + noun (his determination), while the other is a phrase (and the hard work he was willing to do). We need another possessive pronoun + noun: "His willingness to work hard "

Explanation: Riya asked what Rohan was searching for. Alia asked if he had lost something. The mother shouted why he has been roaming around in the neighbourhood so late at night..

We used the second sentence in the option because it suits the format of the indirect speech. The first sentence where it has a question mark it will be ‘asked’ in the indirect speech. The same goes for the second sentence. It has a question mark and so it will be ‘asked’. For the third sentence it will be shouted as given in the sentence. However, the sentence in the question is in a gerund form (verb + ing) so the indirect speech will be in the past continuous too which is present only in the second option.

Here, the first part of the sentence is in simple past tense, so the second part will follow the parallelism and be in the past tense form. Secondly, on the porch is the correct preposition and not at or upon.

Galloway opened the door and turned on the lights when he heard the faint footsteps on the porch.
