Question : Directions: Study the following histogram of marks in mathematics (out of 50) of students in a class and answer the following question.
The percentage of number of passed students is (31 is the pass marks):
Option 1: $85\frac{8}{9}$%
Option 2: $86\frac{8}{9}$%
Option 3: $87\frac{8}{9}$%
Option 4: $88\frac{8}{9}$%
Correct Answer: $88\frac{8}{9}$%
Solution : The total number of students in the class = 15 + 20 + 40 + 50 + 10 = 135 The number of the successful students = 20 + 40 + 50 + 10 = 120 $\therefore$ The percentage of the number of passed students

Question : Consider the given consumption function of country X and answer the following question.
C = 100 + 0.8Y
What is the value of autonomous consumption (A) and marginal propensity to consume (MPC) in the given equation?
Option 1: A = 0.8, MPC = 100
Option 2: A = 100, MPC = 80
Option 3: A = 80, MPC = 0.10
Option 4: A = 100, MPC = 0.8
Correct Answer: A = 100, MPC = 0.8
Solution : The correct option is A = 100, MPC = 0.8.
In the consumption function C = 100 + 0.8Y, autonomous consumption (A) is the constant term, which is 100. The marginal propensity to consume (MPC) is the coefficient of
