Answers :

1) Answer: C

The total classes taken by the professor A in 1 week

= > (3*3) + (4*2) = 9 + 8 = 17

The total classes taken by the professor A in 3 weeks = 17*3 = 51

The total classes taken by the professor D in 1 week

= > (1*3) + (5*2) = 3 + 10 = 13

The total classes taken by the professor D in 4 weeks = 13*4 = 52

Required difference = 52 – 51 = 1 class

2) Answer: A

Total number of classes taken by the professor B in 3 weeks

= > 192000/4000 = 48 classes

According to the question,

(12*3) + 3*(Tuesday + Thursday) = 48

3*(Tuesday + Thursday) = 48 – 36

3*(Tuesday + Thursday) = 12

Tuesday + Thursday = 4 classes

Total number of classes taken by professor B in Thursday = 2 classes

The number of classes taken by the professor B in Thursday in 3 weeks

= > 2*3 = 6 classes

3) Answer: D

The number of classes taken by the professor C in a week

= > (2*3) + (3*2) = 6 + 6 = 12

The number of classes taken by the professor C in 4 weeks

= > 12*4 = 48

The total amount given to the professor C in 4 weeks

= > 48*5000 = Rs. 240000

4) Answer: B

The number of classes taken by the professor A in a week

= > (3*3) + (4*2) = 9 + 8 = 17

The number of classes taken by the professor A in 3 weeks

= > 17*3 = 51

The total amount given to the professor A for 3 weeks

= > 51*3000 = Rs. 153000

The number of classes taken by the professor D in a week

= > (1*3) + (5*2) = 3 + 10 = 13

The number of classes taken by the professor D in 5 weeks

= > 13*5 = 65

The total amount given to the professor D for 5 weeks

= > 65*6000 = Rs. 390000

Required difference = 390000 – 153000 = Rs. 237000

5) Answer: C

The total amount given to the professor B per class = Rs. 4000

The total amount given to the professor C per class = Rs. 5000

Required % = (4000/5000)*100 = 80 %
