A bag contains 1 rupee, 50-paise and 25-paise coins in the ratio 5 : 6 : 7. If the total amount is ₹390, find the number of 25-paise coins |
280 200 240 260 |
280 |
Total amount = 390 1 Rs. 50 P 25 P Number → 5 6 7 In Rupees → 5x \(\frac{6}{2}\) = 3x \(\frac{7}{4}\) = 1.75x
So, (5 + 3 + 1.75)x = 390 (given) 9.75x = 390 x = 40
No. of 25 P coins = 7 × 40 = 280 |
