Answer & Solution
Correct Answer:
Option
A
Ratio of the expenditures of A, B, C, D are as under:
$$\eqalign{ & {\text{A}} \to \frac{{18}}{{40}} = \frac{9}{{20}} = 0.45 \cr & {\text{B}} \to \frac{{21}}{{50}} = 0.42 \cr & {\text{C}} \to \frac{{24}}{{60}} = 0.4 \cr & {\text{D}} \to \frac{{27}}{7} = 0.385 \cr} $$
Clearly, A has done the highest expenditure proportionate to his resources.
$$\eqalign{ & {\text{A}} \to \frac{{18}}{{40}} = \frac{9}{{20}} = 0.45 \cr & {\text{B}} \to \frac{{21}}{{50}} = 0.42 \cr & {\text{C}} \to \frac{{24}}{{60}} = 0.4 \cr & {\text{D}} \to \frac{{27}}{7} = 0.385 \cr} $$
Clearly, A has done the highest expenditure proportionate to his resources.
