Explanation

Atul takes 18 days. Aaravya is 1.5 times as efficient, so she takes 18 / 1.5 = 12 days. The difference is 18 - 12 = 6 days.

AI explanation

Using the efficiency formula, the ratio of time taken by Atul to Aaravya is 150 to 100, which simplifies to 3 to 2. If Atul takes 18 days, Aaravya takes 18 multiplied by 2 divided by 3, equaling 12 days. The difference in their time is 18 minus 12. The result is 6 days.
