Question

Sum of two numbers is 320 their ratio is 5:3 what are the numbers

Answer 1

Step-by-step explanation:

Let the no.s be 5x and 3x

Sum of no.s = 320

5x+3x = 320

8x = 320

x = 320/8 = 40

First no. = 5x = 5*40 = 200

Second no. = 3x = 3*40 = 120

Answer 2

Let the numbers be x and 5x.

So, 5x2 = 320

x2 = 64

x = 8

The numbers are 8 and 40.

Difference between the squares of two numbers = 402 - 82

= 1600 - 64

= 1536
