Question

A certain sum of money amounts to rs 704 in 2 years and rs 800 in 5 years.Fond the principal

Answer 1

Answer:

Now, formula for simple interest (SI) = (P*R*T)/100.

where,

P = Principle,

R = Rate of interest, and

T = Time in years.

If we have to find the total money after certain years, the principle has to be added to the interest earned.

So, Sum = P + SI

Let's go to the question now.

Case 1 : Rs. 1008 in 2 years.

So, 1008 = P + P*R*2/100

Case 2 : Rs. 1164 in 7/2 years

So, 1164 = P + P*R*7/200
