Q 26 If Adam's expenditure is 37.5% more than Andrew's, by what percent is Andrew's expenditure less than Adam's?
​

Answer 1

Given:

If Adam's expenditure is 37.5% more than Andrew's

To find:

By what percent is Andrew's expenditure less than Adam's?

​

Solution:

Let's assume,

"x" → represents Adam's expenditure

"y" → represents Andrew's expenditure

Since Adam's expenditure is 37.5% more than Andrew's, so we can form an equation as:

$x = y + \frac{37.5}{100} y$

$\implies x = \frac{100y\: +\: 37.5y}{100}$

$\implies x = \frac{137.5y}{100}$

$\implies \bold{x = 1.375y}$ ....... (i)

Therefore,

The percentage by which Andrew's expenditure is less than Adam's is,

= $\frac{x\:-\:y}{x}\times 100$

on substituting from (i)

= $\frac{1.375y \:-\: y}{1.375y} \times 100$

= $\frac{0.375 }{1.375} \times 100$

= $\bold{27.27\%}$

Thus, Andrew's expenditure is 27.27% less than Adam's expenditure.
