B. 7.14%

C. 8.87%

D. 6.66%

Answer: Option B

Solution(By Examveda Team)

Cost of fresh mangoes + Cost of packaging = Total cost
Let initial Cost of fresh, mangoes = 100
Then, packaging cost = 40
Thus, Initial total cost = 100 + 40 = 140
After increasing in cost of fresh mangoes 30%,
Cost of fresh mangoes = 130
And cost of packing go down by 50 % so,
Cost of packing = 20
Now Total cost = 130 + 20 = 150
Increased cost = 150 - 140 = 10
% increased = $$ = \frac{{10 \times 100}}{{140}} = 7.14\% $$

    Why did you take 20₹?
    Won't it be 20% of 130 as in the question it is clearly mentioned that the packaging cost is % of fresh fresh mangoes
