Question

The ages Edna, and Elsa are consecutive integers. The sum of their ages is 114. What are their ages?

Answer 1

Edna = 56.5

Elsa = 57.5

Explanation:

Represent Edna age with x; Elsa age will be x + 1

So,

`x + x + 1 = 114`

`2x + 1 = 114`

Make 2x the subject

`2x = 114 - 1`

`2x = 113`

Solve for x

`x = 113/2`

`x = 56.5`

Elsa age is calculated as thus;

`Elsa = x + 1`

`Elsa = 56.5 + 1`

`Elsa = 57.5`
