Question

there are 200 students in a primary school. they need 50 litres of drinking water per day.if 50 of them reduced how many litres oh water needed per day?​

Answer 1

Answer:12.5 Litres per day

Step-by-step explanation:

So 200 students require = 50 llitres of water

So 1 student require =

$\frac{50}{200} \: \: \: litres \\ = \frac{1}{4} \: \: \: litres$

So now if 50 students are reduced then now total no. of students =150

Water required by 150 students will be :-

$\frac{1}{4} \times 50 = 12.5 \: \: \: litres$

So the students require 12.5 lts of water per day.
