Correct Answer: C [2] Explanation: $\frac{180 \times 15 - 12 \times 20}{140 \times 8 + 2 \times 55}$ $=\frac{20 \times 3 [9 \times 5-4]}{10[14 \times 8 +1]}$ $=\frac{6 \times 41}{112+11}\implies \frac{6 \times 41}{123}$ $=6 \times \frac{1}{3}$ $=2$ Nithin K ? answered Apr 21 '2018 at 17:46 All Comments
