Question

40% of the teacher in a school are females and the no. of Male teachers is 42 .Find the total no. of teachers in the school.​Pls answer fast..

Answer 1

Step-by-step explanation:

Let the total no. of teachers in school be = x

No. of male teachers = 42

No. of female teachers= 40% of x = x - 42

A/q

40/100 × x = x - 42

2x/5 = x - 42

2x = 5(x - 42)

2x = 5x - 210

Moving the 5x to LHS

2x - 5x = 210

-3x = 210

Moving -3 to RHS to find x

x = -210/-3

x= 70 teachers

Answer 2

Given: $40$% of the teacher in a school are females and the no. of Male teachers is$42$.

We have to find the total no. of teachers in the school.

We are solving in the following way:

We have,

$40$% of the teacher in a school are females and the no. of Male teachers is$42$.

Let the total number of teachers be$x$.

Percentage of female teachers = $40$%

So, percentage of male teachers = $100 -40= 60\%%$

We have,

The no. of Male teachers is$42$.

So,

$60\%$of$x$$=42$

$\Rightarrow \frac{60}{100} \times x=42\\\\\Rightarrow x=\frac{42\times100}{60} \\\\\Rightarrow x=70$

Hence, the total number of teachers is$70$.
