Question

find the whole quantity is 70% of it is 14 minutes​

Answer 1

let the total quantity be x

70% of x = 14

x = 14 / 70 % ( 70% = 70/100)

X = 20

so whole quantity= 20 minutes

Answer 2

70% of x = 14 minutes

=> (70/100) * x = 14

=> 70x/100 = 14

=> 70x = 14 * 100

=> x = (14 * 100)/70

=> x = 1400/70

=> x = 20 minutes
