Answer 2

Answer:

We can use unitary method:--

                EGGS              MINUTES

                   1                          5

                   4                          ?

Number of minutes taken to boil 1 egg    =5 minutes

Number of minutes taken to boil 4 eggs  =?

                                                                     = 5/1 × 4

                                                                      = 5×4

                                                                       = 20 minutes

Therefore, it takes 20 minutes to boil 4 eggs.
