Step-by-step explanation:

Answer 2

Answer:

Number of MCQs in test = 6

Step-by-step explanation:

let , number of MCQs in test = X

number of FIBs in test = Y

Total numbers of questions = 10

then , X + Y = 10

or , X = 10 - Y ...(1)

According to the question :-

Points for MCQs = 3

Points for FIBs = 8

so , 3X + 8Y = 50 ...(2)

Putting the value of X in (2) from (1)

3 (10 - Y) + 8Y = 50

30 - 3Y + 8Y. = 50

5Y = 50 - 30

5Y = 20

Y = 20 / 5

Y = 4

Again , putting the value of Y in (1) from (2)

X = 10 - Y

X = 10 - 4

X = 6

so,

number of MCQs in test = 6

number of FIBs in test = 4
