They need
50 litre drinking water/ day, if
50
of them are reduced how many
litres
of water needed
needed per day?​

Answer 1

Milk needed for 200 students= 50 litres

Milk needed for 1 student = 50/200

Milk needed for 200-50( 150) students=

$\frac{50}{200} \times 150 \\ = \frac{5}{2} \times 15 \\ = \frac{75}{2} = 37.5 \: l$

Answer 2

Answer: They will need 50 litre per day.

Explanation: Because 50 - 50 = 0. So, we will need more 50 litres. 0 + 50 = 50
