Answer 1

Answer:

₹10 =80notes

₹20=60notes

Step-by-step explanation:

Let the no. of 20 rupee notes be 3x

and 10rupee notes be 4x.

Amount of 10 rupees =(4x*10)rupee

Amount of 20 rupees =(3x*20)rupee

Total amount with him =2000rupee

ATQ:

=(4x*10)+(3x*20)=2000

=40x+60x=2000

=100x=2000

=x=2000/100

=x=20rupee

no. of 20rupee notes=3x=3*20=60

no. of 10rupee notes=4x=4*20=80
