**Answers & Solutions:**

**1)Â AnswerÂ (D)**

Distance travelled by P on Monday = 240 km

Speed = 19.2 kmph

Speed = Distance/Time

Time = $\frac{240}{19.2} = 12.5$ hr

$\therefore$ P took 12 hr 30 minutes to cover the distance.

**2)Â AnswerÂ (B)**

Time taken by truck=time taken by car=distance/speed =256/32

Time taken = 8 hours.

Total distance travelled by car=256+160=416

Avg.speed=total distance/total time

=432/8 =52 km/hr

Option B is the right answer.

**3)Â AnswerÂ (A)**

Least common multipke of 36,27 and 9 is 108.

Hence Harish, Dilip and Asha will meet at 108 second i.e 1 minute and 48 seconds.

Therefore, the correct option is option A.

**4)Â AnswerÂ (D)**

The time of their meeting again can be calciulated by taking LCM of 24, 6 and 14.

LCM of 24, 6 and 14 = 168

Now, 168 seconds = 2 min 48 s.

Option D is correct.

**5)Â AnswerÂ (A)**

1 minute work of tap A = $\frac{1}{60}$

1 minute work of tap B = $\frac{1}{30}$

=> (A + B)’s 1 minute work = $\frac{1}{60} + \frac{1}{30}$

= $\frac{1 + 2}{60} = \frac{3}{60}$

= $\frac{1}{20}$

$\therefore$ Time taken by (A + B) to empty the tank = 20 min

**6)Â AnswerÂ (A)**

Let us first get a relation between the workÂ done by a man, woman and a child.

1 man can do a work in 4*2 = 8 days

1 woman can do the same work in 4*4 = 16 days

1 child can do the same work in 4*5 = 20 days

=> 1 man = 2.5 child and 1.25 woman = 0.8 child

2 men + 4 women + 10 children = 5 + 5 + 10 = 20 children

1 child takes 20 days to complete a work => 20 children will take 1 day to complete the same work.

**7)Â AnswerÂ (A)**

Time taken by 6 men to finish the whole work = 8 days

Let the number of men required be x.

Less days, more men (Inverse Proportion)

Days Men

8 6

2 x

â x =(8 * 6)/2 = 24 men

The additional men required = 24-6 men= 18 men

**8)Â AnswerÂ (C)**

Let the speed of work done by A, B and C be a, b and c.

Now, b=.5c, a=.5b=.25c

c does work in 7 days. It’s speed will be W/7. A’s speed will be .25W/7 and B’s speed will be .5W/7

Their combined speed is 1.75W/7

Time taken by them to complete the work = $\frac{W}{(1.75W/7)}$ = $\frac{7}{1.75}$= 4

Hence, together they will complete the work in 4 days.

Therefore, option C is correct.

**9)Â AnswerÂ (D)**

The number of days 16 men take to complete a piece of work is 7 days.

Hence, the number of days it takes 1 man to complete the piece of work is 7*16 = 112 days.

So, the number of days it takes 28 men to complete the piece of work is $\frac{112}{28} = 4$ days

**10)Â AnswerÂ (B)**

24 men can complete the work in 15 days.

So, 1 man can complete the work in 15*24 = 360 days.

Hence, 18 men can complete the work in $\frac{360}{18}=20$ days
