Answer» Correct Answer - Option 1 : 40 Given: A can complete his office project in 52days B is 30% more efficient than A. Formula Used Work = Time×Efficiency Time is inversely proportional to Efficiency. Calculation Let the days taken by Bto complete the project bex According to the question, The ratio of efficiency of B and A = 130 : 100 The ratio of time taken byBandA= 100: 130 = 10: 13 The time taken by B to complete the project = (52) × (10/13) ⇒ x = (52) × (10/13) ⇒x = 40 ∴ Bwill take 40days to complete the project.

Answer» Correct Answer - Option 1 : 40

Given:

A can complete his office project in 52days

B is 30% more efficient than A.

Formula Used

Work = Time×Efficiency

Time is inversely proportional to Efficiency.

Calculation

Let the days taken by Bto complete the project bex

According to the question,

The ratio of efficiency of B and A = 130 : 100

The ratio of time taken byBandA= 100: 130 = 10: 13

The time taken by B to complete the project = (52) × (10/13)

⇒ x = (52) × (10/13)

⇒x = 40

∴ Bwill take 40days to complete the project.
