Thanks!​

Answer 1

Answer:

Hi

Let the Original pupil in the town = x

Percentage of pupil died = d = 5%

Percentage of pupil remaining left the

town = r = 3%

Now, Number of pupil in the town

= 276450

According to the problem given,

x[(100-d)/100][(100-r)/100 ]= 276450

x[(100-5)/100][(100-3)/100]=276450

x × (95/100)(97/100) = 276450

x = ( 276450 x 100 x 100 )/( 95 x 97)

After cancellation,

x = 300000

Therefore,

Original pupil in the town =X

x = 300000

it may help you sorry if wrong
