The number of 2-rupee coins are three times the number of 5-rupee coins.
How many 1-rupee coins does Kriti have?

Answer 1

Step-by-step explanation:

x - no of 5 rupees coins

y - no of 2 rupees coins

z - no of 1 rupees coins

5x + 2y + z = 41

x+y+z = 20

y = 3x

elimination of variables

4x + y = 21

7x= 21

x = 3

y = 9

z= 8
