Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 1

⇒12.5+47 of 56−12(207÷23×4.5)−2113×(14+18)⇒\frac{12.5 + \frac{4}{7} \ of \ 56 - 12}{(207 \div 23 \times 4.5) - 21 \frac{1}{3} \times \left( \frac{1}{4} + \frac{1}{8} \right)}

⇒12.5+32−12(9×4.5)−2113×( 38) ⇒\frac{12.5 + 32 - 12}{(9 \times 4.5) - 21 \frac{1}{3} \times \left(\ \frac{3}{8} \right)}

⇒12.5+20(9×4.5)−643×( 38) ⇒ \frac{12.5 + 20 }{(9 \times 4.5) - \frac{64}{3} \times \left(\ \frac{3}{8} \right)}

⇒32.5(40.5−8) ⇒\frac{32.5 }{(40.5 - 8 )}

⇒32.532.5⇒ \frac{32.5 }{32.5}

⇒ 11
