IMO 25
1 can concentrate + 3 cans of water = 1 orange juice
let the number of can be X
there fore
12 X + 36 X = 1200 ( 200 * 6 ounces)
solve for X
hence 25.

Hi,
now the ratio of orange juice to water is 1:3
total orange juice is 6 ounce serving * 200 = 1200 ounces of orange juice
this means 300 ounces of orange juice and 900 ounces of water ( ratio 1:3)
300 ounces / 12 ( can size) =25
hope this helps

Maximum no. of 4 letter words out 26 words.. is 26^4
Maximum no. of 5 letter words out 26 words.. is 26^5
hence the total is
26^4 + 26^5
26^4( 1 + 26)
27*26^4
do let me know if u have any doubts..

You can also see it like this:
1/4 of the quantity of orange juice is concentrate so
Use 300 concentrate and 900 water to make 1200 once of orange juice
and 300 divided by 12 is 25
You may find the second one question on the forum.
