There are 450 oranges and mangoes in a fruit stall. There are twice amount of mangoes as there are oranges.

a)how many oranges are there in the stall?

b)2/3 of the oranges are green and the others are ripe. How many oranges are ripe?

c)A box can hold 24 mangoes how many
boxes are needed to pack the mangoes?

number of oranges ---- x

number of mangoes ---- 2x

solve for x:
x+2x = 450

now that you know the number of each, all will fall into place

112.5

To solve these problems, we will use algebraic equations. Let's go step by step.

a) To find the number of oranges in the stall, let's assign a variable. Let's say 'o' represents the number of oranges. It is given that the number of mangoes is twice the number of oranges, so we can write the equation:

Number of Mangoes = 2 * Number of Oranges

We know that the total number of oranges and mangoes is 450, so we can also write:

Number of Oranges + Number of Mangoes = 450

Now, substitute the first equation into the second equation:

Number of Oranges + 2 * Number of Oranges = 450

Simplify the equation:

3 * Number of Oranges = 450

To solve for the number of oranges, divide both sides of the equation by 3:

Number of Oranges = 450 / 3 = 150

Therefore, there are 150 oranges in the stall.

b) Now, let's find the number of ripe oranges. We are given that 2/3 of the oranges are green. So, 1/3 of the oranges must be ripe.

To find the number of ripe oranges, calculate 1/3 of the total number of oranges:

Number of Ripe Oranges = (1/3) * Number of Oranges
= (1/3) * 150
= 50

Therefore, there are 50 ripe oranges.

c) Now, let's calculate the number of boxes needed to pack the mangoes. We know that each box can hold 24 mangoes.

To find the number of boxes needed, divide the total number of mangoes by the capacity of each box:

Number of Boxes = Total Number of Mangoes / Capacity of Each Box
= 450 / 24
= 18.75

Since we can't have a fraction of boxes, we need to round up to the nearest whole number. Therefore, we will need 19 boxes.

To summarize:
a) There are 150 oranges in the stall.
b) There are 50 ripe oranges.
c) We need 19 boxes to pack the mangoes.
