let the ratio be x
then one rupee coin = 5×x
= 5x
two rupee coin = 6x × 2
= 12x
total amount = 85
12x + 5x = 85
17x = 85
x = 85/17
x = 5
two rupee coin = 12× 5
= 60
then one rupee coin = 5×x
= 5x
two rupee coin = 6x × 2
= 12x
total amount = 85
12x + 5x = 85
17x = 85
x = 85/17
x = 5
two rupee coin = 12× 5
= 60
