Ruby has 3 times as many ₹2 coins as ₹5 coins. If she has ₹88 in total, how many ₹5 coins does she have?
A6
B8
C12
D24
Answer & Solution
Correct answer: B. 8
Let the number of ₹5 coins be y. Then ₹2 coins = 3y. Total value: 5y + 2(3y) = 5y + 6y = 11y = 88 → y = 8. So Ruby has 8 ₹5 coins and 24 ₹2 coins (check: 8×5 + 24×2 = 40 + 48 = 88 ✓).
