The average age of 11 players of a cricket team is increased by 2 months when two of them aged 18 years and 20 years are replaced by two new players. The average age of the new players is :

19 years 11 months

Avg. age of two new players = \(\frac{18\;+\;20\;+\;(11\;×\;2\;months)}{2}\)

                                              = \(\frac{38\;+\;22\;months}{2}\)

                                              = 19 years and 11 months
