Question
A bag contains 50 p, 25 p and 10 p coins in the ratio 5: 9: 4, amounting to Rs. 206. Find the number of coins of 25 paisa type?
Answer: Option B
- Let the number of 50 p, 25 P and 10 p coins be 5x, 9x and 4x respectively.
(5x/2)+( 9x/ 4)+(4x/10)=206
50x + 45x + 8x = 4120
103 x = 4120
x=40.
Number of 50 p coins = (5 x 40) = 200;
Number of 25 p coins = (9 x 40) = 360;
Number of 10 p coins = (4 x 40) = 160.
