A bag contains coins of 1 rupee, 50 paise and 25 paise in the ratio of 1 : 2 : 4. If the total money in the bag is ₹ 225, then how many 50 paise coins are there?
Answer & explanation
Correct answer: option 1
Denomination - 1rupee : 50 paise : 25 paise
1 : 2 : 4
Total Amount = (1 x r) + (0.50 x 2r) + (0.25 x 4r) = 225
r + r + r = 225
3r = 225 ⇒ r = 75
No. of 50 paise coins = 2r = 2 x 75 = 150
