Question

The sum of two numbers is 20 and their difference is 5/2 what is the ratio of number

Answer 1

Answer:

let the two no. be x and y

so, x+y=20......(1)

and x-y=5/2........(2)

on adding eq .(1) and (2)

x+y+x-y= 20-5/2

2x= 35/2

x=35/2×2

x=35/4

so the ratio of two no. are 35/4×4/35=1
