O Decrease 40 by ratio of 4:5

Reika [66]

A decrease in the ratio 4:5 implies that :

New quantity:Old quantity = 4:5

Let the new quantity be $\bf \: x$

$\bf∴ x : 40 = 4:5$

$= > \bf \frac{x}{40} = \frac{4}{5}$

$\bf = > 40 \times \frac{x}{40} = 40 \times \frac{4}{5}$

$\bf = > x = 8 \times 4$

$\bf = > x = 32$

So, the new quantity is 32
