Answer 1

Answer:

30

Step-by-step explanation:

Let say one rupee & two rupee coins are  5x & 6x respectively

5x * 1  + 6x *2 = 85

5x + 12x = 85

17x = 85

x = 5

two rupee coin = 6x = 6*5 = 30

Answer 2

Let the number of one rupee and two rupee coins = 5x and 6x

Value of 1 rupee coins= 5x*1=5x

Value of 2 rupee coins=6x*2=12x

Hence

12x+5x=85

17x=85

x=85/17

x=5

Thus no. of rs.1 coin =5*5=25

no. of rs 2 coins = 5*6=30
