Hey there!
To find the greatest common factor you will need to find all the factors of 36 and 54. (A factor is a number that can be divided into another number).
54 - 1, 2, 3, 6, 9, 18, 27.
36 - 1, 2, 3, 4, 6, 9, 12, 18.
As you can see here, the factor that is the greatest is 18. Therefore, that is your answer.
Hope this helps! :)

Answer:
20
Step-by-step explanation:
The cost of the x mangoes was ...
c = 10(x/4)
The revenue from the sale of mangoes was ...
r = 20(x-5)/5
The profit is the difference between revenue and cost:
10 = r - c = 20(x -5)/5 -10(x/4) = 1.5x -20 . . . . substitute and simplify
30 = 1.5x . . . . . add 20
20 = x . . . . . . . .divide by 1.5
The trader bought 20 mangoes.

He paid 20(10/4) = 50 naira. He sold the 15 good mangoes for 20/5(15) = 60 naira, so made a 10 naira profit.
