Question

If two number are in the ratio 7:9 and their sum in 112, find the smaller number

Answer 1

Answer:

let first no = 7x

let second no = 9x

sum = 112

According to question

7x + 9x = 112

16x. = 112

x = 112 / 16

x = 7

so,

first number = 7x = 7 ×7 = 49

second number = 9x = 9×7 = 63

49 is the smaller number .
