1A
2B
3C
4D

Answer:- 1

Explanation:-

Solution:

Ratio of the expenditures of A, B, C, D are as under:

\begin{aligned} A \to \frac{18}{40} = \frac{9}{20} = 0.45 \\ B \to \frac{21}{50} = 0.42 \\ C \to \frac{24}{60} = 0.4 \\ D \to \frac{27}{7} = 0.385. \end{aligned}

$\eqalign{ & {\text{A}} \to \frac{{18}}{{40}} = \frac{9}{{20}} = 0.45 \cr & {\text{B}} \to \frac{{21}}{{50}} = 0.42 \cr & {\text{C}} \to \frac{{24}}{{60}} = 0.4 \cr & {\text{D}} \to \frac{{27}}{7} = 0.385. \cr}$ Clearly, A has done the highest expenditure proportionate to his resources.
