Question

what sum of money will amount to rupees 4230 in two and half years at 7% per annum simple interest

Answer 1

4230*30*7/100*12=740.25+4230=4970.25

Answer 2

Given :

Amount =4230

Time = 2.5 years

Rate of interest =7%

To Find:

What will be the sum?

Solution:

Let the sum of money be x

Amount =4230

SI=Amount - Principal=4320-x

Rate of interest =7%

Time =2.5 years

$Si=\frac{P \times T \times R}{100}\\4320-x=\frac{x \times 2.5 \times 7}{100}\\432000-100x=17.5x$

x=3676.6

Hence The sum is Rs.3676.6
