Ratio between 2 numbers is 5 : 7 and their product is 560.what is the difference between 2 numbers?

Answer»

Let NUMBERS are 5X and 7x



Given, Their product = 560

=> 5x × 7x =560

=> 35x² = 560

=> {x}^{2} = \frac{560}{35} \\ \\ => {x}^{2} = 16 \\ \\ => x = 4



Then,

Their difference

=> 7x - 5x
=> 7( 4 ) - 5( 4 )
=> 28 - 20
=> 8
