Elis [28]

Well, if the selling price was 210, and that's the 100%, then if he adds 60% to that, the new price will be 160% of 210... well, if 210 is the 100%, what's 160% of that?

$\bf \begin{array}{ccllll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
210&100\\
x&160
\end{array}\implies \cfrac{210}{x}=\cfrac{100}{160}$

solve for "x".

A rectangle with a length of 12 cm and a width of 6 cm has an area of 72 sq cm and a perimeter of 36 cm.

frozen [14]

So we should first start off by checking for the ones with the same area, which is 72sq cm

80×90=7200sq cm so A is incorrect

8×10=80sq cm so B is incorrect

3×24=72sq cm so, so far C is correct

4×14=56sq cm so D is incorrect

And because all are incorrect except C
Then C is the correct answer, just to be sure, we will check the perimeter

24+24=48
48+3=51
51+3= 54

So the perimeter is different, making C the correct answer
