Problem

David weighs 62.5kg. If he reduces his weight in the ratio of 5:3. Find his reduced weight.

Hint

Operator used : Ratio

Step

Weight of David

\$62.5\$kg

Step

Let the previous weight be

\$5x\$

Step

\$5x = 62.5\$

Step

\$x = \cancel(62.5)^12.5 / \cancel(5)^1\$

Step

\$x = 12.5\$

Step

Hence, the reduced weight is 3x

3 x 12.5
37.5kg
