Question

a boy was asked to multiply a given number by 8/17 . Instead he divided the given number by 8/17 and got the result 225 more than what he should have got if he had multiplied the number by 8/17 . Find the given number.

Answer 1

let the no. be x
$x \div \frac{8}{17} = 225 \\ \frac{17x}{ 8} = 225 \\ 17x = 1800 \\ x = 105.8$

Answer 2

Answer:

136

Step-by-step explanation:

Let X be the given number

 

X / (8/17) - X(8/17) = 225

 

17X/8 - 8X/17 = 225

 

289X/136 - 64X/136 = 353X/136 = 225

 

Solving for X 1

X = 136
