Question

two nos are in ratio 4:7 if the largest no is 63 find the smaller no

Answer 1

the smaller number is 36.

Answer 2

Let A be the sum of two numbers.

Then, 7/11 x A = 63 (7 is ratio of larger number and 11 is the sum of two ratios)

=> A = 63 x 11/7

=> A = 99

Now, subtracting larger number 63 from the sum of two numbers

i.e 99-63 = 36

Hence, the smaller number is 36.

Hope it helps. Thanks.
