Question

During a tree-planting event, a group of boys and girls planted a total of 150 trees. Each boy planted

10 trees and girl 5 trees. If the number of boys was 10, find the number of girls in the event.
​

Answer 1

Answer:

The number of girls was 10.

Step-by-step explanation:

Number of boys = 10

Total trees planted by them = 10 × 10 = 100

Remaining trees = 150 - 100 = 50

Number of trees planted by girls overall = 50

Number of trees planted by only one girl = 5

Let the number of girls be x,

5x = 50

x = $\dfrac{50}{5}$

x = 10

Hence, there were 10 girls on that event.
