Hope this'll help you out...

Answer 2

The sum that will amount to rs 34300 in 4 years at the same rate of interest per annum is Rs.24500

Step-by-step explanation:

Case 1:

Amount = Rs.19500

Principal = Rs.15000

Simple interest = 19500-15000=4500

Time = 3 years

$SI = \frac{ P \times T \times R}{100}\\\\4500=\frac{15000 \times 3 \times R}{100}\\\\\frac{4500 \times 100}{15000 \times 3}=R\\\\10\% = R$

Case 2:

Amount = 34300

Time = 4 years

Rate = 10%

Let the sum be x

Simple interest = 34300-x

$34300-x=\frac{x \times 4 \times 10}{100}\\\frac{100(34300-x)}{40}=x$

x=24500

Hence The sum that will amount to rs 34300 in 4 years at the same rate of interest per annum is Rs.24500
