Question

Find the principal of the amount for 5 years at 5% is Rs 5550

Answer 1

Your need a small correction after which the question would be as follows:

Find the principal if the amount for 5 years at 5% p.a. is Rs 5550.

Solution:

We have the following information,

Amount, A = Rs. 5,550

Rate of interest, R = 5 % p.a.

Time, T = 5 years

We are not given whether the amount is given/invested at compound interest or simple interest, so we will assume that the principal was given/invested at simple interest.

A = ( P * R * T ) / 100 + P

5,550 = ( P * 5 * 5 ) / 100 + P

5,550 = 25P / 100 + P

5,550 = ( 25P + 100P ) / 100

5,550 * 100 = 125P

125P = 5,55,000

P = 5,55,000 / 125

P = Rs 4,440

Hence,

Principal = Rs 4,440

Answer 2

$\huge \bold {\mathfrak {hey}}$

Given :
Amount = 5550
Time = 5 years
Rate = 5%

To find : Principal

Now,

Amount = (p× r×t) /100 + p

5550 = ( p × 5 ×5)/100 + p

5550 = 25p + 100p / 100

5550 = 125p / 100

5550 × 100 = 125p

555000 = 125p

P = 555000/ 125

P = 4, 440

Therefore Principal is

$\huge {\boxed {Rs. 4,440}}$
