Question

480 books were donated to all the students of class A and each child received 12 books. 640 pencils were distributed to all the students of class B and each child received 10 pencils. What is the total number of students in both classes?

• A. 82
• B. 104
• C. 108
• D. 96

Answer 1

The correct option is B 104

Solution:
Total number of books distributed = 480
Number of books received by each child = 12

$\text{Total number of children who received books}=\frac{\text{number of books distributed in total}}{\text{number of books received by each child}}=\frac{480}{12}$

Total number of pencils distributed = 640
Number of pencils received by each child = 10

$\text{Total number of children who received pencils}=\frac{\text{number of pencils distributed in total}}{\text{number of pencils received by each child}}=\frac{640}{10}$


So, the total number of children who received books is 40 and the total number of children who received pencils is 64.
So, total number of students =40+64=104.
