Question : There are six baskets — Green, Red, Blue, Yellow, Black, and White. Each basket has some rings in it. The average number of rings in all the six baskets is 38. If the blue basket is removed, the average number of rings in the remaining baskets is 34. How many rings are there in the blue basket?
Option 1: 22
Option 2: 45
Option 3: 37
Option 4: 58
Correct Answer: 58
Solution :
The average number of rings in all the six baskets is 38.
The total number of rings in all the six baskets = 38 × 6 = 228
If the blue basket is removed, the average number of rings in the remaining baskets is 34.
The total number of rings in all the five baskets = 34 × 5 = 170
$\therefore$ Rings in blue basket = 228 – 170 = 58
Hence, the correct answer is 58.
