Q. A class has 30 students with an average score of 75. If 5 new students join with an average score of 80, what is the new average? (2023)
A.
76
B.
77
C.
78
D.
79
Solution
Total score of 30 students = 30 * 75 = 2250. Total score of 5 new students = 5 * 80 = 400. New total = 2250 + 400 = 2650. New average = 2650 / 35 = 76.43.
Q. A class has 30 students with an average score of 75. If a new student joins and the average becomes 76, what is the score of the new student? (2023)
A.
80
B.
85
C.
90
D.
95
Solution
Total score of 30 students = 30 * 75 = 2250. New total = 31 * 76 = 2356. Score of new student = 2356 - 2250 = 106.
Q. A class has an average score of 75. If one student scored 90, what is the average score of the remaining students if there are 20 students in total?
A.
74
B.
75
C.
76
D.
77
Solution
The total score of the class is 75 * 20 = 1500. Removing the student who scored 90 gives a new total of 1500 - 90 = 1410. The average of the remaining 19 students is 1410 / 19 = 74.21, which rounds to 74.

A.
10 cm
B.
15 cm
C.
25 cm
D.
30 cm
Solution
Using the mirror formula: 1/f = 1/v + 1/u, where f = -20 cm (concave mirror), v = -30 cm (image distance), we find u = 25 cm.
