Q 1 - Rohan was thrice as old as Rakesh three years ago. If difference of their age is 5 years. Find the age of Rohan?

Options :

Let the present age of Rohan = x,

Present age of Rakesh = x-5, X = 3(x-3-3)

X = 3x - 18X = 9.

Q 2 - A has $3 more than B, but then B wins on the horses and trebles his money, so that he now has $2 more than the original amount of money that the two boys had between them. How much money did A and B have before B's win?

Options :

Let money with A = x. Then, money with B = x + $3. Now, 3x = (x + x + $3) + $2 x = $5.

Therefore total money with A and B = 2x + $3 = $13.

Q 3 - A snail moves up 30 cm when each hour is started and stops for a while when it slips back 20 cm before it again starts climbing in the beginning of the next hour. If it begins its ascent at 8.00 a.m., at what time will it first touch a flower at 120 cm from the ground?

Options :

Let the ascent of the snail in 1 hour = ( 30 - 20 ) = 10 cm.

So, the snail ascends 90 cm in 9 hours i.e., 5 p.m.

Clearly, in the next 1 hour i.e., till 6 p.m.

The snail ascends remaining 30 cm to touch the flower.

Q 4 - Rohan and Hari are two workers and they work for BMA constructions. Rohan is twice as good a workman as Hari. Together Rohan and Hari finish a piece of work in 18 days. In how many days will Rohan alone would finish the work?

Options :

If Rohan takes x days to do a work then Hari takes 2x days to do the same work.

1/x + 1/2x = 1/18

3/2x = 1/18

x = 27 days.

Hence, Rohan alone can finish the work in 27 days.

Q 6 - 16 men and 20 boys can do a piece of work in 30 days. In how many days, 15 men and 15 boys will take to finish the work?

Options :

16 men = 20 boys

1 man = 5/4 boys

15 men = 75/4 boys

Total no of boys = 75/4 + 15 = 135/4

20 boys = 30 days

135/4 boys = 30 × 20 × 4 /135 = 17 7/9 days

Q 7 - Five bells in Oregon begin to ring together and then each bell rings at different intervals. They ring respectively at intervals of 6, 5, 7, 10 and 12 seconds. In one hour how many times they will ring together if the one at the start is excluded.

If LCM will be taken then we can find that they will ring together in every 7 seconds and the number of times they will ring in an hour is 8 times.

Q 8 - P is able to complete a certain task in 6 days and Q can do it within 8 days. P and Q agreed to do the task together for Rs. 4000. R joined them and they finished the task within 3 days. How much is to be paid to R?

Options :

$Work \: done \: by \: R \: in \: one \: day \: = \: \frac{1}{3} - \lgroup\frac{1}{6} + \frac{1}{8}\rgroup = \frac{1}{3} - \frac{7}{24} = \frac{1}{24}$

$P's share \: : \: Q's share \: : \: R's Share \: = \: \frac{1}{6} : \frac{1}{8} : \frac{1}{24} = 4 \: : \: 3 \: : \: 1$

$\therefore \: R's \: share \: for \: 3 \: days \:= \: Rs.\lgroup3*\frac{1}{24}*4000\rgroup \: = \: Rs.500.$
