.A bag contains 20 coins of denominations of ₹ 2 and ₹ 1. The total amount in the bag is ₹ 30. Find the number of coins of each denominations.​

Answer 1

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.
