Question

Two numbers are in the ratio 5:8 and their difference is 12. Find the numbers

Answer 1

let,
first no. be x
second no. be y
given
x-y=12
x/y=5/8
x=y5/8
5/8y-y=12
y=-32
x=-20

Answer 2

Ratio given =5 : 8

Let the common term be x

So,

Larger number = 8x

Smaller number = 5x

Now,
=> 8x - 5x = 12

or, 3x = 12

or, x =4

Now, the large number = 8×4 = 32

The smaller number = 5×4 = 20
