Answer:
Rupees 1 coins = 10
Rupees 2 coins = 10
Step-by-step explanation:
Let number of Rupees 2 coins be "x"
Then,number of Rupees 1 coins be (20-x)
Amount of Rupees 2 coins is 2*x = 2x
Amount of Rupees 1 coins is 1*(20-x) = 20-x
According to the Question,
2x + 20-x = 30 (Rupees)
x + 20 = 30
x = 30-20
x= 10
Hence, number of Rupees 2 coins and 1 coins are 10 each.
