Question 1158141

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?
<pre>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 {{{highlight_green(matrix(1,6, S, "=", 105/3, "=", 35, years-old))}}}
