Question

Find a number such that if 16 is added to it, the ratio of the result to the original number is 4:3

Answer 1

48

Explanation:

let the number be x and x + 16 the result of adding 16 to it, then

the ratio of the result to the original is

`(x+16)/(x)` =
`(4)/(3)` ( cross- multiply )

4x = 3(x + 16) = 3x + 48 ( subtract 3x from both sides )

x = 48
