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)
