please tell me the anwer step by step it's my request​

Answer 1

Sizes : 90,95,100,90,90,95,95,100,90,105

Modal size = Size that belongs to many shirts, i.e., that size which is repeated the maximum time and belongs to the greatest no. of shirts = 90 (because 90 is the size that exists many times)

Now in case of one shirt, which was initially sized as 95, you are considering it 90 by misreading it.

So, now we can say the sizes are : 90,90,100,90,90,95,95,100,90,105 (90 instead of 95)

In this case, modal size is the same, i.e., till now modal size = 90.

90 is the size number that is present maximum times !
