we have to find the cans of conc to make 200*6 =1200 oz of juice

let conc of cans be x and water be 3x.
Hence in to make orange juice of 4 oz we have 1 oz of concentrate.
Can is 12 oz each.

Hence in 48 oz of juice we have 12 oz of conc and 36 oz water.

1200 oz juice, x oz of conc

x = 12/48 ) * 1200 = 300 oz of conc

A can is 12 oz each. Hence no of cans = 300/12 = 25

You get 200*6 which is 1200 ounces of Orange juice

We know in the Orange juice the ratio of concentrate : water is 1:3

Con
----- = 1 /3
Water

Total parts = 4

1/4 th of 1200 is concentrate which is 300 ounces

Since we have 12 ounce cans of concentrate
we need 300/12 = 25 cans

simple maths
1+3 =4

50 +150 = 200
these are for 6 ounce.

But in qs it is asked 12 ounce so .. 25
