Question

on a particular day 16% of the students in a class remained absent. If 42 students were present on that day find the total strength of the class​

Answer 1

Answer:

50

Step-by-step explanation:

Given,

16% of the students in a class remained absent.

So,

Percentage of students present = (100 - 16)% = 84%

Also given that,

42 students were present on that day.

That means, 84% of the total strength is equal to 42 students.

Let the total strength be x.

So,

84% of x = 42

$\frac{84}{100} \times x = 42$

Thus,

$x = \frac{42 \times 100}{84}$

$x = 50$

Thus, the total strength of the class is 50.

Hope it helps.

Have a nice day ☺

Answer 2

Answer:

The total strength of the class is 50

Step-by-step explanation:

Let total students be x

Absent =

100/16*x

Present =x−16x/100*42

⇒84/100*x = 42

x= 100*42/84

= 100/2

= 50

So x=50= Total strength
