66 is the 100%
we can solve this problem by the rule of three.
Therefore:
66------------------------100%
x--------------------------150%
x=(66 * 150%) / 100%=99
Answer 150% of 66 is 99.
Other method:
150% of 66=1.5 *66=99
Answer: 150% of 66 is 99.
Its either 3 or 2
the third way matches only if there's another reference line
I'll go with 3
20 * (31/100) = 21*0.31=6.51
20.00-6.51=13.49

As x and y vary directly then <span>x∝y</span> i.e. <span>x=ky</span>, where k is a constant.
When <span>x=24</span>, <span>y=8</span> i.e. <span>24=k×8</span> and therefore
<span>k=<span>248</span>=3</span>
and relation between x and y is hence <span>x=3y</span>
and when <span>y=9</span>, <span>x=3×9=27</span>.
I hope this is what you're looking for.
Answer and explanation:
67% as it's +/- one standard deviation from the mean
