Answer 2

Answer:  Sum is Rs. 675 and Rate of interest = 8%.

Step-by-step explanation:

Since we have given that

Amount in 2 years = Rs. 783---------(1)

Amount in 3 years = Rs. 837-----------(2)

Subtract (2) - (1), we get that

$837-783= Rs. 54$

So, Simple Interest in (3-2=1) yr = Rs. 54

Simple interest in 2 years is given by

$54\times 2=Rs. 108$

so, Principal will be

$783-108\\\\=Rs. 675$

Now, we will find "Simple Interest "

$108=\frac{675\times R\times 2}{100]\\\\R=8\%$

Hence, Sum is Rs. 675 and Rate of interest = 8%.
