Show answer & explanation

Correct answer: D

Explanation

The correct answer is option 4 i.e. 738\frac{73}{8}.

⇒ 8−5÷23×3+(7÷7×7)÷7+(3×6÷13)×1338 - 5 \div 2^3 \times 3 + (7 \div 7 \times 7)\div 7 + (3 \times 6 \div \frac{1}{3})\times \frac{1}{3^3}

⇒ 8−58×3+(77×7)×17+(3×6×3)×1338 - \frac{5}{8} \times 3 + (\frac{7}{7}\times 7) \times \frac{1}{7} + (3 \times 6 \times 3) \times \frac{1}{3^3}

⇒ 8−158+1+28 - \frac{15}{8} + 1 + 2

⇒ 11−15811 - \frac{15}{8}

⇒ 88−158\frac{88 - 15}{8} = 738\frac{73}{8}
