1
If in 2017, the average fee per student as well as the number of students is increased by 20% and 10% respectively from 2016 in class A, then what is the total revenue generated from class A in the year 2017? 
» Explain it
A
Number of students in class A in 2016 = 22% of 1000 = 220

Average fee per student in class A in 2016

= 800 ×  67.5  = Rs. 150
360

Number of students in class A in 2017 = 110% of 220 = 242

Average fee per student in class A in 2017 = 120% of 150 = Rs.180

Total revenue generated from class A in the year 2017 = Number of students × Average fee per students = 242 × 180 = Rs.43560

Hence, option A is correct.
2
Total revenue generated from class C in 2016 is approximately what percent of the total revenue generated from class E in 2016?
» Explain it
B
Total revenue generated from class C in 2016 = Number of students × Average fee per students

⇒ (16% of 1000) ×  800 × 49.5  = Rs.(160 × 110)
360

Total revenue generated from class E in 2016 = Number of students × Average fee per students
 
⇒ (19% of 1000) ×  800 × 72  = Rs.(190 × 160)
360

Reqd. % =  160 × 110  × 100 = 57.89 ≈ 58%
190 × 160

Hence, option B is correct.
3
What is the ratio of the total revenue generated from class E in 2016  to the total revenue generated from class F in 2016 if number of students in class F is 20 more than the number of students in class B in 2016 and average fee per student in class F is Rs.50 more than the average fee per student in class B in 2016?
» Explain it
C
Total revenue generated from class E in 2016 = Number of students × Average fee per students

⇒ (19% of 1000) ×  800 × 72  = Rs.(190 × 160)
360

Number of students in class F = (18% of 1000) + 20 = 180 + 20 = 200

Average fee per student in class F
= 800 ×  90  + 50 = 200 + 50 = Rs.250
360

Total revenue generated from class F = Rs.(200 × 250)

Required ratio = (190 × 160) : (200 × 250) = 76 : 125

Hence, option C is correct.
4
What is the approximate average fee per student of classes C, D and E together in 2016?
» Explain it
C
Average fee per student =  Total fee
Total students

Total fee of class C = (16% of 1000) × [800 ×  49.5  ]
360

= 160 × 110 = Rs.17600
 
Total fee of class D = (25% of 1000) × [800 ×  81  ]
360

= 250 × 180 = Rs.45000
 
Total fee of class E = (19% of 1000) × [800 ×  72  ]
360

= 190 × 160 = Rs.30400

Total fee of classes C, D and E together = Rs. (17600 + 45000 + 30400) = Rs. 93000

Total students in classes C, D and E together = 160 + 250 + 190 = 600
 
Reqd. average = Rs.  93000  = Rs. 155
600

Hence, option C is correct.
5
If in 2015, the number of students in class D was 50% more than the number of students in class D in 2016 and average fee per student of class D was 10% less than the average fee per student of class D in 2016, then what was the total revenue generated from class D in 2015?
» Explain it
D
Number of students in class D in 2015 = 150% of 25% of 1000 = 375

Average fee per student of class D in 2015

= 90% of [800 ×  81  ]  = Rs.162
360

Total revenue generated from class D in 2015 = 375 × 162 = Rs.60750

Hence, option D is correct.
