Answer:
The no of coins of 50p is 400
The no of coins of 25p is 600
The no of coins of 20p is 800
Step-by-step explanation:
As given , the bag contains Rs 510 in the form of 50p, 25p and 20p coins in the ratio of 2:3:4.
First convert the coins values in Rupee ,i.e. Rs 0.50, Rs 0.25 and Rs 0.20
Let the total number of coins are 2x, 3x, 4x
=> 0.50x * 2x + 0.25 * 3x + 0.20 *4x = 510
=> x + 0.75x + 0.80x = 510
=> 2.25x = 510
=> x = 200
The no of coins of 50p is 2x = 2*200 = 400
The no of coins of 25p is 3x = 3*200 = 600
The no of coins of 20p is 4x = 4*200 = 800
