Explanation:

Let there be x one rupee coin, y 50 paise coin, z 25 paise coinx + y + z = 220......(i)

Total amount = 160

Now, x + (y/2) + z = 160 ......(ii)

⇒4x + 2y + z = 640

Thrice as many 1 re coin as 25 paise

⇒x = 3z ......(iii)

On solving equation (i), (ii) and (iii), we get

z = 40x= 3* 40 = 120y = 220 –(120 + 40 ) = 60

So, 50 paise coin =60
