the sale of flower by alin,izzati and damia are in the ratio 3:9:7.the difference between the sales by alin and dania is rm 36.how much did izzati get from her sales?
let their sales be 3x, 9x, and 7x
7x - 3x = 36
4x = 36
x = 9
sales:
alin = 27
izzati = 81
damia = 63
check:
difference between alin and damia
= 63-27
= 36
To find out how much Izzati earned from her sales, we need to determine the value of izzati's share in the ratio.
Let's assume the total sales made by Alin, Izzati, and Damia is represented by the variable "x".
The given ratio is 3:9:7, which means that the total ratio is 3 + 9 + 7 = 19.
To find out the value of izzati's share, we need to divide the total sales by the total ratio and then multiply it by the individual ratio for Izzati, which is 9.
izzati's share = (total sales/total ratio) * izzati's ratio
izzati's share = (x/19) * 9
Now, let's set up an equation using the information that the difference between Alin's and Damia's sales is RM 36:
Alin's share - Damia's share = RM 36
To get the values for Alin's and Damia's share, we'll use the ratio values:
Alin's share = (x/19) * 3
Damia's share = (x/19) * 7
Substituting the values into the equation:
[(x/19) * 3] - [(x/19) * 7] = 36
We can now solve this equation to find the value of x, which represents the total sales:
3x/19 - 7x/19 = 36
(3x - 7x)/19 = 36
-4x/19 = 36
-4x = 36 * 19
-4x = 684
x = 684/-4
x = -171
However, sales cannot be negative, so there seems to be an error in the question.
Please double-check the given values or provide any additional information if there are any further details.
