Answer:
There are total 18 girls and (30 - 18) = 12 boys.
Step-by-step explanation:
- Suppose there are 'x' girls in the class. Each girl drew a square.
A square contains 4 sides. Each girl drew 4 sides.
x girl drew 4x sides.
- In the class there are total 30 students. Number of boys = 30 - x
Each boy drew a pentagon that means 5 sides.
Number of sides drew by boys = 5(30 - x)
- Total number of sides drew by all the students = 4x + 5(30 - x)
From the mentioned data, 4x + 5(30 - x) = 132
150 - x = 132
x = 150 - 132 = 18
∴ There are total 18 girls and (30 - 18) = 12 boys.
