Answer: (D)

$20$

(d) Let the person have $Rs.100$. For $Rs.100$, he can purchase either $50$ oranges or $40$ mangoes, i.e., cost of one orange $=Rs.2$
and cost of one mango $=Rs.2.50$. Now he keeps $Rs.10$ for taxi fare and buys $20$ mangoes for which he pays $Rs.50$.
He is left with $Rs.40$ with which he can buy $20$ oranges.
