Question

during an epidemic 4/25 of the people in the village died and 420 were left, how many died?​

Answer 1

Step-by-step explanation:

Let the total no. of people in the village be x.

people died= 4/25× x

I.e, 4x/25

people left= x-4x/25

b/c,

x-4x/25=420

=> (25x-4x)/25=420

=> 21x/25=420

=> x= (420×25)/21

=> x=100

So the no of people died is 4/25×100= 16
