CorrectNot quiteAnswer D
Correct answer: D
Explanation
Increasing every bill by 5% multiplies each by 1.05 and keeps their order the same.
So the median is also multiplied by 1.05: = ₹882.
Worth noting
₹845 adds ₹5 instead of 5%, and ₹798 decreases by 5%. The median does change when every value is scaled.
