Question

what sum will amount to rupees 5525 at 10% per annum simple interest in 3 years

Answer 1

HERE'S YOUR ANSWER.....✌️✌️

Let the principal be p,

S.I. = A - P = 5525-p

Amount = ₹5525
Rate = 10%
Time = 3 years

5525 - p = p × 10 × 3/100

=> 5525 - p = 30p / 100

=> 552500 -100p = 30p

=> 552500 = 130p

=> p = 552500/130

=> p = 4250

Therefore, the sum is ₹ 4250.

Answer 2

Answer:

The answer is 4250 Rs.

Step-by-step explanation:

Given problem

what sum will amount to rupees 5525 at 10% per annum simple interest in 3 years

here given that the resultant amount A = 5525

                        rate of simple interest R = 10%

                                          time period T = 3 years

let P be the principal amount or the sum amount

then interest on P at rate 10% for 3 years  I = $\frac{PTR}{100}$

                                                                       = $\frac{P(3)(10)}{100}$

                                                                       = $\frac{3P}{10}$  

the resultant amount A = P + I

              => $\frac{3P}{10} +P = 5525$    [ from given data ]

              => $\frac{13P}{10} = 5525$  

              => 13P = 55250

              => P = 4250 Rs
