Question 106

Raman is 25% more efficient than Aman. If Aman can complete a piece of work in 25 days, then Raman can complete the same work in how many days?

Solution

Let Aman's efficiency = 1 unit/day

=> Total work to be done = $$1\times25=25$$ units

Raman is 25% more efficient than Aman, => Raman's efficiency = $$1\times\frac{125}{100}=1.25$$ units/day

$$\therefore$$ Time taken by Raman working alone = $$\frac{25}{1.25}=20$$ days

=> Ans - (D)
