Question

If there are $50$ mangoes in a box, how will you write the total number of mangoes in terms of the number of boxes? (Use b for the number of boxes.)

Answer 1

Express number of mangoes in terms of number of boxes

Given, $50$ mangoes are in a box.
Let $b$ be the number of boxes.

Thus,
Total number of mangoes $=$ Number of mangoes in each box $\times$ number of boxes
Total number of mangoes $=50\times b=50b$

Hence, the total number of mangoes is $50b$.
