What are those two numbers whose sum is 58 and difference is 28’?

1.	What are those two numbers whose sum is 58 and difference is 28’?
Answer» Let the bigger number be ‘x’. The sum of two numbers = 58 ∴ Smaller number = 58 – x The difference of two numbers = 28 ∴ x – (58 – x) = 28 x – 58 + x = 28 2x = 28 + 58 = 86 ∴ x = \(\frac{86}2\) = 43 ∴ Bigger number or one number = 43 Smaller number or second number = 58 – 43 = 15

Answer»

Let the bigger number be ‘x’.

The sum of two numbers = 58

∴ Smaller number = 58 – x

The difference of two numbers = 28

∴ x – (58 – x) = 28

x – 58 + x = 28

2x = 28 + 58 = 86

∴ x = \(\frac{86}2\) = 43

∴ Bigger number or one number = 43

Smaller number or second number = 58 – 43 = 15
