4 girls : 2 boys

compare ratios with the answer choices.

4:2 =\= 4:8

4:2 =\= 8:6

4:2 =\= 6:9

A sold a commodity to b at 10% profit b again sold it to a at 10% loss. What does a have
ozzi
Let's answer this step-by-step.

First of all, let's estsblish the original price of the commodity as being 100%. Therefore:

Original price of commodity = 100%

Then, when A sold the commodity to B, it was sold at a 10% profit. Therefore:

Price of commidity when A sold to B:
100% x 1.1 = 110%

After that, when B sold it back to A, it was sold at a 10% loss. Therefore:

Price of commodity when B sold to A:
110% x 0.9 = 99%

Hence, A now has 99% of the original value of the commidity.

If A = {x | x is an even integer}, B = {5, 6, 7, 8}, list the elements of the set A U B
ahrayia [7]
First of all, what is an integer?

Integers are numbers such as -7, -4, 0, 5, 16... etc...

This means that even integers are numbers such as:

-4, -2, 0, 2, 4, 6, 8, 10... etc...

Which means that:

AUB={..., -4, -2, 0, 2, 4, 5, 6, 7, 8, 10, 12, 14, ...}

This is because:

The union "<span>U</span>" of two sets must contain all the numbers from both sets, providing they aren't duplicated.
