Question

Amit is twice as good as Ramit. Working together they can complete the work in 28 days. In how many days can Ramit alone can do the same whole work?

1. 64
2. 74
3. 84
4. 94
5. 54

Answer 1

Correct Answer - Option 3 : 84

Given:

Efficiency of Amit = 2 × Efficiency of Ramit

Concept used:

Total work = Efficiency × Time period

Calculation:

The efficiency of Amit = 2

Efficiency of Ramit = 1

Total work = (2 + 1) × 28 = 3 × 28 = 84

Number of days Ramit takes to complete the whole work = 84/1 = 84

∴ The number of days in Ramit will complete the work is 84 days.
