therefore coins of 50 paisa are 3x
amount of 1 rupee coin = 1×x=100x paisa
amount of 50 paisa coins=50×3x=150 paisa
100x+150x=4500
250x=4500
x=18

Answer 2

Answer:

let no. of 1rupee coin= x

no. of 50 paisa coin= 3x

total amount= 35 =4500 paisa

amount of 1rupee =1x =100x paisa

amount of 50 paisa=50 *3x=150 paisa

A.T.Q

100x + 150x= 4500

250x = 4500

x =4500/250

x = 18

3x=54
