Question

The mean of 8 is 25.If each number is multiplied by 3, what will be the new mean?​

Answer 1

Answer:

75

Step-by-step explanation:

Given, Mean of 8 is 25, i.e., (x1 + x2 + ........ +x8) / 8 = 25.

                                                               ∑x = 25 x 8 = 200

If each number is multiplied by 3, ∑x = 200 x 3 = 600

                                  New Mean = ∑x/n = 600/8

                                                     = 75
