Answer 2

Step-by-step explanation:

Amount =Rs. 180

Let ratio be x

let amount of 1 rupees coin be 2x

let amount of 50 paise coins be 3x

let 25 paise coins be 4x

Amount of Rs. 1 coin = Rs. 1 * 2x

= Rs. 2x

Amount of 50 paise coins = Rs. 1/2 * 3x

= Rs. 3x/2

Amount of 25 paise coins = Rs. 1/4 * 4x

= Rs. x

2x + 3x/4 + x = Rs. 180

Taking L.C.M. as 4

8x/4 + 3x/4 + 4x/4 = 180

15x/4 = 180

15x = 180 *4

15x = 720

x = 720/15

x= 48

amount of 50 paise coins = 3x

= 3 * 48

= 144 coins
