Download Solution PDFGiven:
A can do the work in 63 days.
B is 40% more efficient than A.
Formula used:
If B is 40% more efficient than A, then B will take less time to complete the same work. The time taken by B is inversely proportional to their efficiency.
Calculation:
Let the efficiency of A be 100 units. Then the efficiency of B is 140 units.
Time taken by B = (Efficiency of A / Efficiency of B) × Time taken by A
⇒ Time taken by B = (100 / 140) × 63
⇒ Time taken by B = (5/7) × 63
⇒ Time taken by B = 45 days
∴ The number of days taken by B to do the same work is 45 days.
