Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 60.5.
The marks obtained in Geography by P = 0.88 × 75 = 66
The marks obtained in Geography by Q = 0.92 × 75 = 69
The marks obtained in Geography by R = 0.64 × 75 = 48
The marks obtained in Geography by S = 0.80 × 75 = 60
The marks obtained in Geography by T = 0.88 × 75 = 66
The marks obtained in Geography by U = 0.72 × 75 = 54
So, the total marks obtained in Geography = 66 + 69 + 48 + 60 + 66 + 54 = 363
Hence, the average marks obtained in Geography = 363/6 = 60.5
