ARITHMETIC MEAN-2

Find the arithmetic mean of 60 and 70.

Solution

a = 60, b = 70.

Arithmetic Mean(AM) = a + b

                                           2

Arithmetic Mean(AM) = 60 + 70

                                            2

Arithmetic Mean(AM) = 130

                                          2

Arithmetic Mean(AM) = 65.

∴ Arithmetic Mean(AM) is 65.
