Question
Rohit multiplies a number by 5454 instead of 4545 by mistake. Find the error percent.
Options:
- 52.56%
- 20%
- 25%
- 56.25%
Solution
To find the error percent, we first need to understand the nature of the error. Rohit was supposed to multiply a number by 4545 but he multiplied it by 5454 instead.
Step 1: Find the difference between the correct and incorrect multiplication factor. Difference = 5454 - 4545 = 909
Step 2: Find the error percent. The error percent is calculated by dividing the difference by the correct multiplication factor and then multiplying by 100 to get a percentage. Error percent = (Difference / Correct multiplication factor) * 100 Error percent = (909 / 4545) * 100 = 20%
So, the error percent is 20%.
