Question

plzzzzz give ans 18to20​

Answer 1

Step-by-step explanation:

Total no. of denomination = Rs.120

No. of Rs. 5= x

No. of Rs. 2= 2x

No. of Rs. 1 = 60 - (2x +x)

= 60-3x

A/q

5(x) + 2(2x) + 60 -3x =120

or 5x + 4x + 60 - 3x = 120

or 9x-3x+60 = 120

or 3x = 120-60

or x = 60÷3

x= 20

No. of Rs. 5 = 20

No. of Rs 2= 2*20 = 40

No. of Rs . 1 = 60 -(40 +20)

= 60 - 60

= 0
