D.0.0666

Answer 1

Answer:

0.0714

Step-by-step explanation:

Let the intial cost be '1'.

=> 1 + 0.4 = 1.4

Cost of mangoes is increased by 30% and packing is deacreased by 50%.

=> 1.3 + 0.2 = 1.5

Increase in cost = (1.5 - 1.4)

                          = 0.1

% increased = [(0.1)/1.4] * 100

                    = 7.14%

                    = 0.0714.

Hope it helps!
