Question

1. 70
2. 25
3. 60
4. 50
5. 56

Answer 1

Correct Answer - Option 3 : 60

Given:

Raja + Ram = 30 days

Raja worked = 16 days

Ram finishes rest = 44 days

Formula used:

Total work done (1/T) = (1/T1) + (1/T2) + (1/T3)

Where, T, T1, T2, T3 is time taken to complete the work in days

Calculation:

Assuming raja’s one day of work to be X and ram’s as Y

⇒ X + Y = (1/30)      ….(1)

⇒ 16X + 44Y = 1      ….(2)

Solving equation 1 and 2

⇒ X = 1/60

⇒ Y = 1/60

∴ Ram can alone finish the work in 60 days.
