​of ₹150​

Answer 1

Answer:

number of coin of Rs. 10 = 3x

number of coin of Rs. 5 = 7x

number of coin of Rs. 2 = 30 - (3x + 7x) = 30 - 10x

total = Rs. 150

(3x*10) + (7x*5) + 2(30 - 10x) = 150

30x + 35x + (60x - 20) = 150

45x = 150 - 60

x = 90/45 = 2

number of 10 Rs. coin = 3x = 6

number of 5 Rs. coin = 7x = 14

number of 2 Rs. coin = 30 - 10x =10
