Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e 156/67.

= 515÷[312−56−(35+110−415)]5\frac15÷[3\frac{1}{2}-{\frac{5}{6}-{(\frac{3}{5}+\frac{1}{10}-\frac{4}{15})}]} can be written as,

= 26/5 ÷ [7/2 - 5/6 - (3/5 + 1/10 - 4/15)]

= 26/5 ÷ [7/2 - 5/6 - (18 + 3 -8)/30]

= 26/5 ÷ [7/2 - 5/6 - 13/30]

= 26/5 ÷ [(105 - 25 - 13)]/30

= 26/5 ÷ [67/30]

= 26/5 × 30/67 = 156/67
