Answer:
x = 4
2x = 8
5x = 20
Step-by-step explanation:
No. of 50 paise coins = x
No. of Rs. 1 coins = 2x
No. of Rs. 2 coins = 5x
Value of 50 paise coins = x * 0.50 = Rs. 0.5x
Value of 1 Rs. coins = 2x * 1.00 = Rs. 2x
Value of 2 Rs. coins = 5x * 2.00 = Rs. 10x
Total value = Rs. 50
0.5x + 2x + 10x = 50
12.5x = 50
x = 4
then, 2x = 2*4=8
5x = 5*4=20
