Give the ans in steps.

Answer 1

Answer:

300489

Step-by-step explanation:

Let original no of pupil in the town be (100)

now 5% of it. died < 100-5%=95% > <will use 95% as we've to calculate remaining pupils

therefore we're left with 100*0.95 pupils now

3% of remaining left the town i.e.

100*0.95*0.97 = 92

now this

92 = 276450

and we have to calculate for 100.

1 = 276450/92

100=276450/92*100 = 300489
