Answer: Each student will have 12 pencils.
Step-by-step explanation:
Given: Total students= 25
Total colored boxes = 15
Total pencils in 1 box =20
Then total pencils in all 15 boxes = 20 × 15 = 300
Now, the number of pencils each students will get = (Number of pencils in all 15 boxes) ÷ (Total students)
= 300÷ 25
= 12
Therefore, Each student will have 12 pencils.
