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 :

A - 3AM

B - 6PM

C - 5PM

D - 9AM

### Explanation

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.

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

3/2x = 1/18

x = 27 days.

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

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

20 boys = 30 days

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

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

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