Question

If 20% of a number is 35 , what is 50 % of that number

Answer 1

87.5

Explanation:

let a number be x

20% of x = 35

20/100 * x = 35

1/5 * x = 35

x = 35*5

x = 175

50% of x

50/100 * 175

1/2 * 175

87.5

Answer 2

87.5

Explanation:

Using proportion

20% → 35

50% → 35 ×
`(50)/(20)` =
`(35(50))/(20)` = 87.5
