Answer 2

Given: Ray can complete a piece of work in 15 days.

To find: We have to find the percentage of work that will be completed in 7.5 days.

Solution:

Let the total work be 100 units.

In 15 days Ray can complete 100 units of work.

Thus in 7.5 days, Ray can complete 100×7.5/15=50 units of work.

Total work is 100 units.

Work completed 50 units.

Thus the percentage of work completed is-

$\frac{50}{100} \times 100 = 50$

Thus 50% of work has been completed in 7.5 days.

The correct option is D.
