Show answer & explanation

Correct answer: A

Explanation

The correct answer is option 1  i.e. 36

Explanation:

From the given question,

5(1−x5)−(5−x)−20−x200=81005(1-{x\over5}) - (5-x) - {20-x\over 200} = {8\over 100 }

⇒ 5−5x5−(5−x)−(20−x)200=81005 - {5x\over 5} - (5-x) - {(20-x)\over200 }= {8\over 100}

⇒ (5−x)−(5−x)−(20−x)200=8100(5-x) - (5-x) - {(20-x)\over200} = {8\over 100}

⇒ (x−20)200=8100{(x- 20)\over 200} = {8\over 100}

⇒ x = 16 + 20 = 36

Hence the value of x is 36.
