Answer 1

Answer:

1. Average rainfall for 5 years = Total rainfall in 5 years ÷ 5 years

                                                 =  $\frac{900+650+450+733+400}{5}$

                                                 =  $\frac{3133}{5}$

                                                 = 626.6

∴ The average rainfall in Vidarbha for 5 years was 626.6 mm.

2. Average weight of the sacks =

                                       Total weight of all the sacks ÷ Total number of sacks

                                        = $\frac{49.8+49.7+49.5+49.3+50+48.9+49.2+48.8}{8}$

                                        = $\frac{395.5}{8}$

                                        =  49.4

∴ The average weight of the sacks is 49.4 kg.
