Sushil's age = x
Sara's age = x + 7
June's age = x - 4

x + (x + 7) + (x - 4) = 87

x + x + 7 + x - 4 = 87

3x + 3 = 87

3x = 84

x = 28

Sushil's age = x = 28
Sara's age = x + 7 = 28 + 7 = 35
June's age = x - 4 = 28 - 4 = 24

The eldest among then, Sara, is 35.

Sara is 7 years older than Sushil. June is 4 years younger than Sushil. If the total of their ages is 87, how old is the eldest of them?
It's quite obvious from reading this that Sara is the eldest

Let Sara's age be S

Then Sushil's is S - 7, and June's is: S - 7 - 4, or S - 11

We then get: S + S - 7 + S - 11 = 87

3S - 18 = 87

3S = 105

Sara, or
