Answer 1

$\huge{SOLUTION:}$

The question is simple to find out the number of boys and total strength in class 7 with given data.

Given data:

% of girls: 60

Number of girls: 18

Hidden data:

% of boys :40 (100–60)

To find :

• Number of boys in class ?
• Total number of students in class?(once we find answer for first question we can get second answer easily)

Let's come to solution part,

We need to find % of boys

If 60%= 18

Then 40%=X(Let's consider number of boys as X)

Cross multiple the above steps to find number of boys

60%*X= 40%*18

Cancellation of zeros and percentage in above step,

6*X = 4*18

6X= 72

Cancellation of common factor ,

6X=6*12

Hence X=12

Number of boys in class= 12

Total number of students in class= Number of boys +Number of girls

Total number of students in class=12+18

Total number of students in class=30
