Railway TTE Mock Test - 3 - Question 41

A can complete a work in 18 days, B can complete the same work 12.5% more efficiently than A. In what time, A
and B can complete the same work working together?

Detailed Solution for Railway TTE Mock Test - 3 - Question 41

Given:
Days taken by A to complete the work = 18 days
B is 12.5% more efficient than A
Concept used:
Efficiency is inversely proportional to the time.
Calculation:
12.5% = 18
Let efficiency of A be 8 units
And efficiency of B be 9 units.
A : B (Efficiency) = 8 : 9
A : B (Time) = 9 :8
From this,
Time taken by A = 9 units
⇒ 9 units = 18 days
⇒ 1 unit = 2 days
⇒ 8 units = 2×8 = 16 days
Take L.C.M. of 16,18 and make it as total work i.e. 144 units Total work =144 units
Total efficiency A+B = 8+9 = 17 units
Time taken = 144/17 = 8(8/17)
∴ The time taken by A and B to complete the work together is 8(8/17) days.

Railway TTE Mock Test - 3 - Question 42

If a train with a speed of 60 km/hr crosses a pole in 30 seconds, what is the length of the train in metres?

Given,
Speed of train = 60 km/hr = (60×(5/18))m/s
= 50/3 m/s
Time taken = 30 seconds
As we know,
Distance = speed × time
= (50/3) x 30
= 500 m/s
So, length of the train is 500 m.

Railway TTE Mock Test - 3 - Question 43
