Explanation:

According to the given question,

  $61{{3}\over5}\div[40\div2$ of $5+27\div{{1}\over3}-$ $(78\div3{{1}\over3})]$ 

⇒ ${308 \over 5} \div [40 \div 10 + 27 \div {1 \over 3} - (78 \div {10 \over 3})]$

⇒ ${308 \over 5} \div [40 \div 10 + 27 \div {1 \over 3} - {234 \over 10}]$

⇒ ${308 \over 5} \div [4 + 81 - {234 \over 10}]$

⇒ ${308 \over 5} \div {616 \over 10}$

⇒ ${308 \over 5} \times {10 \over 616}$ = 1

HEnce the required answer is 1.
