ratio in which conc and water should be mixed is 1:3

first we will find amount of conc and water required to prepare 1 "6" ounce of orange juice

x+3x=6(as ratio is 1:3)
4x=6
so, x=1.5 i.e. for every 1.5 ounce of conc there will be 4.5 ounce of water.

we need to find for 200 servings, so it will come to 200*1.5= 300 ounce

total 12 ounce cans required will be 300/12 i.e. 25(ans)

A.

Need to prepare 200 *6 ounces of juice --> 1200 ounces

Ratio of concentrate to water is 1:3.

To prepare 1200 ounces of juice, we need (1/4th of 1200)ounces of concentrate --> 300

1 can contains 12 ounces of concentrate --> 25 cans will contain 300 ounces of concentrate. Hence, A.

What is the OA ?
