Question

John weights 65.7 kg. If he reduces his weight in the ratio 5 : 4, find his reduced weight.​

Answer 1

Let the previous weight be 5x.

`\small\bold\pink{ →}\small\bold{5x = 65.7 }`

`\small\bold\pink{ →}\small\bold{x =(65.7)/(5)}`

`\small\bold\pink{ →}\small\bold{x = 13.14}`

Therefore, the reduce weight = 4 × 13.14

= 52.56 kg

Answer :- 52.56 kg
