# In a bag, the number of one rupee coins is three times the number of two rupees coins. If the worth of the coins is ₹ 120, find the number of 1 rupee coins

**Solution:**

Let the number of two rupees coins be x

Then the number of one rupee coins be 3x

The required linear equation is:

2x + 3x = 120

5x = 120

x = 120/5

x = 24

Hence, 3x = 72

Thus, the number of 1 rupee coins is 72.

**✦ Try This:** In a bag, the number of five rupee coins is four times the number of two rupees coins. If the worth of the coins is ₹ 110, find the number of five rupee coins.

Let the number of two rupees coins be x

Then the number of five rupee coins be 4x

A/Q

2x + 5(4x) = 110

2x + 20x = 110

22x = 110

x = 110/22

x = 5

Hence, 4x = 20

Thus, the number of five rupee coins is 20.
