Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e. 6.

Given that

= $({{86\div20}})-{13\over8}of$ $({{1} \over 3}-$ ${{2} \over 13})+$ $({{1} \over 8}\div$ ${{3} \over 7})+($ $2 -{{3} \over 10})$

= $({{43\div10}})-{13\over8}of$ ${{7} \over 39}+$ ${{7} \over 24}+$ ${{17} \over 10}$

= ${{43\over10}}-$ ${{7} \over 24}+$ ${{7} \over 24}+$ ${{17} \over 10}$

= (43/10) + (17/10)

= 60/10 = 6
