Let the total number of 5 rupee coins be x.
Given that number of 2 rupee coins is 3 times the number of 5 rupee coins.
Then, the number of 2 rupee coins = 3x.
Total number of 5 rupee coins + 2 rupee coins = x + 3x
= 4x.
Given that total number of coins = 160.
So, number of 1-rupee coins = 160 - 4x.
-----------------------------------------------------------------------------------------------------------------
So now, we have
Number of 1-rupee coins = 160 - 4x.
Number of 2-rupee coins = 2 * 3x = 6x.
Number of 5-rupee coins = 5x.
Given total amount = 300.
= > 5x + 6x + 160 - 4x = 300
= > 11x - 4x + 160 = 300
= > 7x = 300 - 160
= > 7x = 140
= > x = 20.
----------------------------------------------------------------------------------------------------------------
Therefore,
Number of 5-rupee coins = 20.
Number of 2-rupee coins = 3 * 20
= 60
Number of 1-rupee coins = 160 - 4 * 20
= 160 - 80
= 80.
Hope this helps!
