Question

When x is added to each term of 7:13 the ratio becomes 2:3. The value of x is?​

Answer 1

Answer: x = 5

              The ratio is 12:18

Step-by-step explanation:

Lets add x to both the numbers.

Then the ratio becomes : (7+x) : (13+x)

But the ration is 2:3

Hence,

    (7+x) : (13+x) = 2:3

=> 3(7+x) = 2(13+x)

=> 21+3x = 26+2x

=> 3x-2x = 26-21

=> x = 5

Hence the ratio is (7+5) : (13+5) = 12:18
