RRB Group D Mock Test - 16 - Question 8

A motor boat whose speed is 15 km/hr in still water goes 30 km downstream and comes back in 4 hrs and and 30 minutes. Determine the speed of the stream.

Detailed Solution for RRB Group D Mock Test - 16 - Question 8

Let x km/hr be the speed of water
The speed of motor boat in still water is 15 km/hr, therefore, its speed downstream is (15 + x) km/hr and the speed upstream is (15 - x) km/hr
Time taken for given 30 km downstream = 30/15 + x hours
Time taken for going 30 km upstream = 30/15 - x hours
Since the total time is given to be 4 hours 30 minutes
∴ 30/15 + x + 30/15 - x = 9/2 hours (given)
or 30(15 - x) + 30(15 + x) (15 + x)(15 - x) = 9/2
or 900/225 - x2  = 9/2
or 1800 = 9(225 - x2)
or 200 - 225 + x2 = 0
or x2 = 25
⇒ x = 5, - 5
∴ x = 5 [as x cannot be negative so x = -5 is rejected]
Hence the speed of water = 5 km/hr

RRB Group D Mock Test - 16 - Question 12

The Compound Interest on a certain sum for 2 yrs is Rs 618 whereas the simple interest on the same sum at the same rate for 2 yrs is Rs 600. The rate of interest p.a is

Detailed Solution for RRB Group D Mock Test - 16 - Question 12

Let P be the principal amount and r be the rate of interest
CI – SI = 618 – 600 = 18
P[(1 + r/100 )2 – 1] – (P x r x 2)/100 = 18
P( r 100 )2 = 18 ………(1)
Also we have 2Pr/100 = 600 ⇒ Pr = 30000
Put value of Pr in (1)
We get, r = 6, rate = 6%

RRB Group D Mock Test - 16 - Question 70

If 20 men or 24 women or 40 boys can do a job in 12 days working for 8 hours a day, how many men working with 6 women and 2 boys take to do a job four times as big working for 5 hours a day for 12 days?

Detailed Solution for RRB Group D Mock Test - 16 - Question 70

Amount of work done by 20 men = 24 women = 40 boys
or amount of work done by 1 man = 1.2 women = 2 boys.
The man hours required to complete the new task = 4 times the man hours required to complete the old task. (As the new task is 4 times as big as the old task)
So, the new task is 20 x 12 x 8 x 4 men hours task.
Let 'n' be the number of men required to complete the new task.
Equating the men hours of task, we get 20 x 12 x 8 x 4 = n x 5 x 12. Or n = 128.
The new task will require 128 men, if only men worked on the task to complete it.
However, the problem states that 6 women and 2 boys are working on the job.
6 women are the equivalent of 6/1.2 = 5 men and 2 boys = 1 man.
i.e., the equivalent of 5 + 1 = 6 men are already working on the project.
Therefore, 122 more men are required to work with 6 women and 2 boys to complete the task.
