John increased the amount of water he drinks everyday from 20 fl oz to 48 fl oz. By what percent did John increased the water he drinks?

140%

Step-by-step explanation:

Percentage change in any variable is given by

percentage change = (new value - old value)/ old value * 100

Given

Earlier amount of drinking water = 20 fl oz

New amount of drinking water = 48 fl oz

Percentage increase in drinking of water = (48-20)/20 * 100 = 28/20 * 100

Percentage increase in drinking of water =  28*5 = 140 %

Thus, there is 140% percentage increase in water by John.
