Question

The ratio of two numbers is 5 : 7 .If 40 is added to each of the numbers, the ratio of the numbers

become 25 : 31 find the numbers​

Answer 1

Answer:

here, let the ratio of two numbers =5x and 7x

if 40 added in the each number =5x+40/7x+40=25/31

= 31(5x+40)=25(7x+40)

=155x+1240=175x+1000

=155x-175x=1000-1240

=-20x=-240

x=-240/-20

x=12

5x=5×12=60

7x=7×12=84

is the answer
