Answer 1

Answer:

total number of problems on the test = 50

Step-by-step explanation:

Let say total number of problems in Test = x

28% of Problems of Test completed by by student

28 % of problem = (28/100) x = 7x/25

Student has completed 14 problem

so 7x/25 = 14

=> x/25 = 2     ( dividing by 7 both sides)

=> x = 2 * 25  (multiplying by 25 both sides)

=> x = 50

total number of problems on the test = 50
