Step-by-step explanation:
total notes=35
no of 10rs notes+no of 20 rs notes =35 (given)
suppose no 10rs notes=x
then no of 20rs notes =35-x
total amont=3500
amount of 10rs notes+amount of 20 rs notes=3500
10*x+20(35-x)=3500
10x+700-20x=3500
-10x=3500-700
-10x=2800
x=-2800/10
x=-280
:but total notes 35 i think question is wrong
