Question

After 2 years, at the rate of 4.8% per annum compounded annually, the amount is 1,25,000. Find the initial amount.​

Answer 1

Given :-

• Rate = r = 4.8%

• Time = t = 2 years

• Amount = Rs. 125000

To Find :-

• The Initial amount ; Principle = p = ?

Solution :-

To find Principle :-

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

$:\implies\sf{125000 = P (1 + 4.8/100)^2}$

$:\implies\sf{125000 = P ( 1048/1000)^2}$

$:\implies\sf{ P= 125000 \times 1000 \times 1000/1048 \times 1048}$

$:\implies\sf{ P=Rs. 113,811.84}$

Hence, the initial amount is Rs. 113,811.84.

Answer 2

QUESTION

After 2 years at the rate of 4.8% per annum compounded annually the amount is Rs 125000. Find the intial amount

SOLUTION

AMOUNT=125000rs

TIME=2years

AMOUNT=P(1+R/100)^n

125000=P(1+4.8/100)^2

125000=P(1+48/1000)^2

ON SOLVING,

125000=P(17161/15625)^2

125000×15625/17161=P

113811.84=P

HENCE,INITIAL AMOUNT(PRINCIPAL) IS 113811.84 RUPEES
