In a college, there are 14 girls and 7 boys in chemistry, 10 girls and 18 boys in mathematics, and 15 girls and 20 boys in physics departments.

Question

How much students are there in the college?

Answer 1

To find the total number of students in the college, we need to add the number of girls and boys from each department.

1. Chemistry:

   • Girls: 14
   • Boys: 7
   • Total in Chemistry = 14 + 7 = 21

2. Mathematics:

   • Girls: 10
   • Boys: 18
   • Total in Mathematics = 10 + 18 = 28

3. Physics:

   • Girls: 15
   • Boys: 20
   • Total in Physics = 15 + 20 = 35

Now, let's add the totals from all three departments:

\[ \text{Total Students} = (Total in Chemistry) + (Total in Mathematics) + (Total in Physics) \]

\[ \text{Total Students} = 21 + 28 + 35 \]

Calculating that:

\[ 21 + 28 = 49 \]

\[ 49 + 35 = 84 \]

Therefore, the total number of students in the college is 84.
