Question

what sum will amount to ₹6600 in 2year at 10% per annum simple interest

Answer 1

SI=PRT/100
P=RS.6600
R=10%
T=2yrs
now we just need to apply the formula
SI=6600×10×2/100=RS.1320
Amount=SI+P
=1320+6600=7920

Answer 2

Answer:

The principal amount is ₹5500.

Step-by-step explanation:

Let the principal amount be x.

It is given that the sum in 2year at 10% per annum simple interest amount to ₹6600.

Formula for simple interest.

$I=\frac{P\times r\times t}{100}$

Where, P is principal, r is rate of interest and t is times in years.

$I=\frac{x\times 10\times 2}{100}$

$I=0.2x$

Amount is the sum of principal and interest.

$A=P+I$

$A=x+0.2x$

$6600=1.2x$

$\frac{6600}{1.2}=x$

$5500=x$

Therefore the principal amount is ₹5500.
