Answer:let all the details be x as we know they have same value
Step-by-step explanation:formula= P×N×R/100 = SI
put the values x*x*x/100=x^3= 100x
x^3/100=
x cancel x on both the sides of “=”
we get–x^2/100
sending 100 to the other side
x^2 = 100so, x= 10 is ur answer
proof:- as we know the question ask us the sum means principle
x*10*10/100=10
x*100/100=10 100s' get cancel we get x= 10 hence proved
or ; 10*10*10 /100= 10 is our SI )2 nd proof end...
