this is my question:

"Proper tea" is made by putting milk and tea together in the ratio 2:9. How much "proper tea" can be made using 1 litre of milk?

would i be 5 cups of tea?

Hello andyboy179No, it will be lots more than that!

With litre of milk, you will need litres of tea. So, together with the milk, you'll get litres of "proper tea".

A typical cup will hold about 200 to 250 ml. So you'll get 4 to 5 cups from a litre. Altogether, then, you'll get around 22 to 28 cups of "proper tea" from a litre of milk.

in proper tea ratio of milk(say m) and tea (say t) is 2:9 or

m:t=2:9

if milk is 1 litre there for quantity of tea should be

1:t=2:9 or

t=9/2 litre

or t= 4.5 litre

so total liquid quantity is 1+4.5 litre =5.5 litre

now suppose there are n cups with volume v (i litre) then 5.5 litre milk can be put in 5.5/v cups

or n=5.5/v

but same formula can be used in different way i.e

v=5.5/n

so for n=1 i.e if only one cup is used its volume should be 5.5 litre.

if n=2 its volume should be 2.75 litre

in general 5.5 litre of liquid can be filled in any number of cups

therefor answer is

any natural number (**according to it 5 is also correct**)

(though one may neglect those values of n for which v is non-terminating decimal value.)
