Question

They make a base of 50 gallons (20%). They make a "heavy batch of 150 gallons (80%) They mix them both. What is the percent of them both

Answer 1

The percentage when both quantities gets mix = 65 %

Explanation:

Given as :

The quantity of base = 50 gallons

Now 20% of 50 gallons =
`(20)/(100)` × 50

I.e 20% of 50 gallons = 10 gallons

Again

The quantity of heavy batch = 150 gallons

Now 80% of 150 gallons =
`(80)/(100)` × 150

I.e 80% of 150 gallons = 120 gallons

Now, Total new quantity = 10 gallons + 120 gallons = 130 gallons

And initial total quantity was = 50 gallons + 150 gallons = 200 gallons

∴ percentage when mix both of them =
`(130)/(200)` × 100

I.e percentage when mix both of them = 65 %

Hence The percentage when both quantities gets mix = 65 % answer
