Question

An adult need to take in 3L 500mL of water every day .1L 250ml goes into the body with food every day. How much water should an drink every week?

Answer 1

So 1L 250ML of water goes with the food,

and he need to take 3L 500ML Of water per day

subtracting  1L 250ML from 3L 500ML u get 2L 250ML of water which he need to consume per day other than the amount consumed while eating,

One day 2L 250ML so one week will be 7*(2L 250ML), for simpler calculation multiply ( 7* 2L ) and (7*250ML) separately and add them ,

by doing so u get 14L and 1750ML, 1750ML is equal to 1L 750ML, so by adding 14L and 1L 750ML u get 15L 750ML which is the total amount of water he need to consume per week,

Hope this is helpful
