Amit starts from Lucknow at 12:30 pm and travels to Agra. After reaching Agra, he waits there for 4 hours and then starts his return journey at a speed which was two-third of his earlier speed. He reaches Lucknow at 10:45 pm. At what time did he reach Agra?

3 pm

B

C

3:45 pm

D

Doubt

Sir how is this proportionality approach
Total travel time = 6.25hrs
Speed 1 : speed 2 = s : 2/3s
Speed ratio 3s:2s
Time ratio - 2s : 3s
Time to reach agra = 6.25 * 2/5 = 2.5hrs from 12:30 = 3 pm

Which of the following is true based on the passage?

A

Jews were not as spiritual as the Christian Europeans.

B

Judaism was never identified with materialism before 1870s.

C

Only Jews identified their religion with a particular socio-economic system.

D

Jewish materialists neither believed that Judaism was a religion nor accepted that it was formed on abstract concepts.

option C is somewhat close b reading last line of 2nd para.

When I solved it, I got one solution as 1/5. How did you get 1/4 on your first try?... since the equations have 2 solutions, getting one forces us to redo the whole problem......
