Answer 2

Answer:

Ans. 3,00,000

Step-by-step explanation:

Let there are totally x pupils in the town.

5% of x is = x/20 died due to some disease

left pupil of that town is (x-x/20)

Again 3% of them is equal to (x - x/20) ×3/100 left the town.

So, Remaining pupils of that town is 2,76,450.

which means, x - x/20 - {(x-x/20)×3/100} = 2,76,450

=> x- x/20 - 3x/100 + 3x/2000 = 2,76,450

=> 2000x - 100x - 60x + 3x = 2,76,450 × 2000

=>1843x = 2,76,450 ×2000

=> x = (2,76,450× 2000)/1843

= 3,00,000 (Ans)
