Average Quants MCQs with Answer - Exercise IV


Ques 1 Average


The average weight of 17 boxes is 92 kg. If 18 new boxes are added, the new average increase by 3 kg. What will be the average weight of the 18 new boxes.?
  a) 98.8 kg
  b) 91.8 kg
  c) 97.8 kg
  d) 92.8 kg


c is the correct option
The original 17 boxes have a total weight of 17 * 92 kg.
When 18 boxes are added, the overall average increases by 3 kg, meaning the new total average is 95 kg.
The total weight for all the boxes (17 + 18 = 35) is then 35 * 95 kg.
To find the total weight of the new boxes, subtract the original weight: (35 * 95) - (17 * 92).
Finally, divide this total weight by 18 to get the average weight of the new boxes.
Total weight of new boxes: (35 * 95) - (17 * 92) = 1765 kg.
Average weight of new boxes: 1765 kg / 18 = 97.83 kg (approximately).
The average weight of the 18 new boxes is approximately 97.8 kg.
So the closest answer is (c).
