Question

A is 50% more efficient than B. If B can complete a work in 33 days, how many days will A take to complete the same work?
1. 11
2. 22
3. 33
4. 30

Answer 1

Correct Answer - Option 2 : 22

Given:

A is 50% more efficient than B.

B can complete a work in 33 days.

Formula used:

Total Work = Efficiency × Days

Calculation:

50% more = + ½

That is, if efficiency of B = 2 then efficiency of A = 2 + 1 = 3

⇒ E_A = 3, E_B = 2

∴ Total Work by B = Efficiency × Days = 2 × 33 = 66

∴ Time taken by A to complete the same work = 66 / E_A = 66/3 = 22 days.
