Evaluate: 5−[25÷{13+(13×(1−12))}]5-[\frac{2}{5}\div\{\frac{1}{3}+(\frac{1}{3}\times(1-\frac{1}{2}))\}]

Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1 i.e. 21521\over5.

Given, 5−[25÷{13+(13×(1−12))}]5-[\frac{2}{5}\div\{\frac{1}{3}+(\frac{1}{3}\times(1-\frac{1}{2}))\}]

⇒ 5−[25÷{13+(13×12)}]5-[\frac{2}{5}\div\{\frac{1}{3}+(\frac{1}{3}\times\frac{1}{2})\}]

⇒ 5−[25÷{13+16}]5-[\frac{2}{5}\div\{\frac{1}{3}+\frac{1}{6}\}]

⇒ 5−[25÷ 12]5-[\frac{2}{5}\div\ \frac{1}{2}]

⇒ 5−[25× 2]5-[\frac{2}{5}\times\ 2]

⇒ 5−455-\frac{4}{5} = 21/5
