Answer: Option B

Solution(By Examveda Team)

Day	1	2	3
Initial mangoes	x (let)	0.45x	0.2025x
Sales	0.5x	0.225x	0.10125x
Over night remaining	0.5x	0.225x	0.10125x
Rotten	0.05x	0.0225x	0.010125x
Next day stock	0.45x	0.2025x

Thus, Total mangoes rotten amount is
⇒ 0.05x + 0.0225x + 0.010125x = 0.082625x = 1983
x = 24,000
