Question

# The number of students in Classes III, IV and V are 155,139 and 118. Estimate the total number of students in the three classes taken together.

- 412
- 400
- 420
- 410

Hint:

### We have to find the estimated total number of students in the three classes taken together. First we need to find the sum of the number of students of classes taken together, than we have to round off the sum of the numbers.The derived number will be the required estimated total number of the students in the three classes taken together.

## The correct answer is: 412

### The number of students in III class =155

The number of students in IV class =139

The number of students in V class =118

Sum of the total numbers of students.

=155+139+118

=412

So, 400 is the estimated total number of students in the three classes taken together.
