Question

$\frac{753\times 753\times 247\times 247-753\times 247}{753\times 753\times 773+247\times 247\times 247}=$?

• A. $\frac{1}{1000}$
• B. $\frac{1}{506}$
• C. $\frac{253}{500}$
• D. None of these

Answer 1

The correct option is A $\frac{1}{1000}$

Given Exp.$=\frac{(a^2+b^2-ab)}{a^3+b^3}=\frac{1}{(a+b)}=\frac{1}{(753+247)}=\frac{1}{1000}$
