Step-by-step explanation:
1
let number of 5 rupee coin be x
number of 2 rupee coin is 3x
total value of 5 rupee coin = number of coin× value of coin
=5x
total value of 2 rupee coin = 6x
5x+6x=77
11x= 77
X=7
number of coins are 7 and 21

150x+100x+250-80x=590
170x=340
x=2
the number of coins are 6 10 9
