​

Answer 1

✬ Sum = Rs 12,100 ✬

Step-by-step explanation:

Given:

• Amount (A) is Rs 13,310.
• Rate is 10% per annum.
• Time is 1 year.

To Find:

• What is the sum i.e Principal?

Solution: Let the principal be P.

As we know that

★Amount = Principal(1 + Rate/100)^n★

$\implies{\rm }$ A = P(1 + R/100)^1

$\implies{\rm }$ 13310 = P(1 + 10/100)¹

$\implies{\rm }$ 13310 = P(100 + 10/100)¹

$\implies{\rm }$ 13310 = P(110/100)¹

$\implies{\rm }$ 13310 = 110P/100

$\implies{\rm }$ 13310 $\times$ 100 = 110P

$\implies{\rm }$ 1331000 = 110P

$\implies{\rm }$ 1331000/110 = P

$\implies{\rm }$ Rs 12,100 = P

Hence, the sum is Rs 12,100 .

Answer 2

Step-by-step explanation:

Amount=13310

Rate=10%

Time=1 year

let take P the principal

then amount=principal (1+rate/100)*n

13310=p(1+10/100)¹

p=1331000/110

p=Rs. 12100

hence the answer is 12100
