Answer 1

Answer:

★ 33 Students ★

Step-by-step explanation:

Given:

• There are between 24 and 40 students in a class.
• In one class the ratio of boys to girls is 4:7

To Find:

• How many students are in class?

Solution:

★ If we divide the class into two groups with 4 boys and 7 girls in each group then there will be 11 students in each group ★

∴ The total number of the students in the class should be a multiple of 11

and the only multiple of 11 between 24 & 40 is 33.

∴ There are 33 students in the class

A/q, Their ratio is 4:7

$\small\implies{\sf }$ Number of boys = 4/11 x 33 = 12 Boys

$\small\implies{\sf }$ Number of girls = 7/11 x 33 = 21 Girls

Hence, There are 33 students in class

★ Check ★

• 12/21 = 4/7 or 4 : 7
