Question

the ratio of 2 natural numbers is 5 is to 6.if a certain number is added to both the numbrrs,the ratio becomes 7is to 8.if the larger number exvrefa smaller by 10.find the number added

Answer 1

Let Numbers be 5x and 6x

And 6x -10 = 5x

    so, x = 10

Hence, Numbers are 50 and 60

Let y is added to both sides

Hence, 50+y/60+y = 7/8

      so, 400 + 8y = 420 + 7y

             y = 20

Hence, Number added is 20.
