Question
Rajiv wanted to subtract 5 from a number. Unfortunately, he added 5 instead of subtracting . Find the percentage change in the result.(A) 300%(B) 66.66%(C) 50%(D) Cannot be determined
Solution
To solve this problem, we need to understand that Rajiv's mistake led to a difference of 10 from the intended result. This is because he added 5 instead of subtracting 5, which means the result is 5 (added) + 5 (should have been subtracted) = 10 more than what it should have been.
Now, we need to calculate the percentage change. The formula for percentage change is:
Percentage Change = (Change in Value / Original Value) * 100%
In this case, the change in value is 10 (as calculated above). However, we don't know the original value (the number Rajiv wanted to subtract 5 from), so we cannot determine the percentage change.
Therefore, the answer is (D) Cannot be determined.
