Rohit multiplies a number by 2 instead of dividing the number by 2. Resultant number is what percentage of the correct value?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 400%
Let the number be x
Rohit multiplies a number by 2 = x × 2 = 2x
but Rohit divided that number by 2 = x/2
2x × 100/(x/2) = 4 × 100 = 400%
