Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 352
Number of members = 13 + 10 + 45 = 68
Amount spent by group A = 13 × 367 = 4771
Amount spent by group B = 10 × 112 = 1120
Amount spent by group C = 45 × 401 = 18045
Total amount spent = 4771 + 1120 + 18045 = 23936
Total average per member = 23936 ÷ 68 = 352
