Correct Answer: Rs. 8750

Solution : Let the Principal amount be $P$.
Difference between Compound Interest and Simple Interest for 2 terms = $\frac{PR^{2}}{100^{2}}$ where $R$ is the rate of interest per term and $P$ is principal.
Here $R$ for six months = $\frac{16}{2}$% = 8%
So, 56 = $P[\frac{8^2}{100^2}]$

Correct Answer: 2.508

Solution : Given: $\frac{(3.254 \times 3.254 \times 3.254)-(0.746 \times 0.746 \times 0.746)}{(3.254 \times 3.254)+(0.746 \times 0.746)+(3.254 \times 0.746)}$
Let $a=3.254$ and $b=0.746$
= $\frac{a^3-b^3}{a^2+b^2+ab}$
= $\frac{(a-b)(a^2+b^2+ab)}{a^2+b^2+ab}$
= $a-b$
Putting the values, we get:
= 3.254 – 0.746
= 2.508
Hence, the correct answer is 2.508.
