D Correct answer
Explanation

Akshat = 2 * Lokesh (efficiency). Together = 3 * Lokesh. 3 * Lokesh * 7 days = Total work = 21 * Lokesh. Lokesh alone takes 21 days.

AI explanation

Let Lokesh's efficiency be 1 unit per day, so Akshat's efficiency is 2 units per day. Their combined efficiency is 3 units per day, meaning the total work is 3 multiplied by 7, which equals 21 units. Lokesh alone will finish the 21 units at a rate of 1 unit per day, taking 21 days.
