Question

The sum of two numbers is 125. Their difference is 47. The two numbers are:

a)39 and 86.
b)40 and 85.
c)47 and 78.
d)None of these choices are correct.

Answer 1

A

Explanation:

To find the sum of 125, you have to add the numbers.

39+86 = 125

To find the difference of 47, you have to subtract the numbers.

86-39 = 47

Answer 2

let x represent the bigger number

x+x-47=125

2x-47=125

2x=125+47

2x=172

2x/2=172/2

x=86

the smaller number=x-47

86-47

39

therefore the answer is a) 39 and 86
