P = Rs. 1000 R = 5 % T = 2 Years Find SI .

SI = 1000 X 5% X 2/100 (Rs. X Years)

= 1000 X 5 X 2/10000 (Rs. X Years)

= 1 (Rs. within given Years)

According to Physics fundamentals .

Why not we use % Sign with number value ?

But generally we use % sign only for Given Section, We not use % sign in Solution.

Thats why The formula of SI should be P X R X T.
