Question

two numbers are there ratio3:5.if each number is increased by 10,the ratio becomes 5:7.the numbers are

Answer 1

3x+5x+10=5x+7x
8x+10=12x
12x-8x=10
4x=10
x=2.5

therefore 3:5=7.5 : 12.5
and 5:7 = 12.5 : 17.5

Answer 2

ANSWER
........

$3x + 5x + 10 = 5x + 7x \\ 8x + 10 = 12x$
$12x - 8x = 10 \\ 4x = 10 \\ x = 25$
THEREFORE

3 = 7.5

12.5 = 17.5
