Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 282.
Given that, average of 17 numbers = 47
Each number is multiplied by 6.
If each number in a set of numbers is added, subtracted, multiplied or divided by a number then average of those numbers is also added, subtracted, multiplied and divided by the same number.
According to the given question,
Initial average = 47
New average = 47 × 6 = 282
Hence the new average is 282.
