Let the age of the younger person be x years.
Then, age of the elder perosn = (x + 16) years.
∴ 3(x - 6) = (x + 16 - 6) ⇔ 3x - 18 = x + 10

A lemonade stand sold only small and large cups of lemonade on Tuesday. 3/5 of the cups sold were small and the rest were large. If the large cups were sold for 11/5 as much as the small cups, what fraction of Tuesday's total revenue was from the sale of large cups? | [
"(d) 22/37",
"(b) 7/15",
"(e) 1/2",
"(a) 7/16"
] | A | A simpler way i guess would be to think that in total 5 cups were sold. Out of which 3 are small and 2 are large. Now let the small ones cost $5. so the large ones would cost $11.
So,
3*5=15 and 2*11=22.
Total revenue was 15+22=37
and Large cup sales as found above is 22
Therefore answer is 22/37
