'...as the sexy tutor pulled her black car into the parking lot downstairs...' '...regular joss sticks sessions for the past 18 years...' Given that the legal age for driving in SG is 18 years old, and assuming this is Miss Loi's first tuition assignment ('inexperienced'), and that as of this year she has 18 years of experience... We can deduce that Miss Loi is at least 36 years old. LOL! :) '... a fresh inexperienced but sexy maths tutor ...'

You should be able to park just like in the video :) It's just a simple handbrake parking... just go in screaming (I meant the speed of the car but if you want to accompany it with real screaming, go ahead), yank the handbrake, turn the wheel.

Similar to the <a href="/questions/e-maths/which-ice-cream-cone-should-she-choose" rel="nofollow">earlier ice-cream cones question</a>, it is vitally important for students to stay awake and open their eyes to see what <em>dimensions</em> are the stated ratios pertaining to. To re-cap: Let <var>l<sub>x</sub></var> and <var>l<sub>y</sub></var> be the heights of the small and big diamond respectively. Note that <var>l</var> can also refer to length or width or any one-dimensional unit. For Area: <m>A_x/A_y = (l_x/l_y)^2</m> Since the question states that 9:49 refers to the ratio of the <em>area</em>, <m>9/49 = (l_x/l_y)^2</m> <m>l_x/l_y = sqrt{9/49} = 3/7</m> And as already mentioned, in the strange world of Similarities, the price <em>IS</em> the volume (not sure about this in the real world though :P) So for volume: <m>V_x/V_y = (l_x/l_y)^3</m> From above you already have <m>l_x/l_y = 3/7</m> So <m>V_x/V_y = (3/7)^3</m> Now <i>Ah Beng</i>'s small diamond (<var>V<sub>x</sub></var>) costs $1000, which means <del>Miss Loi's</del> the tutor's humongous diamond (<var>V<sub>y</sub></var>) costs: <m>V_y = 1000/{(3/7)^3}</m> = $12704 (correct to the nearest dollar)!!! Scary isn't it? But then that's only what the <i>Ah Beng</i> calculated with his new-found math skills ... once again things are always a bit different in the real world - Miss Loi's may be too 'calculative' to wear that ... but on the other hand, if it's free ... *drools* Yes Kiroii, you're right!

Similar to the earlier ice-cream cones question, it is vitally important for students to stay awake and open their eyes to see what dimensions are the stated ratios pertaining to.

To re-cap:

Let lx and ly be the heights of the small and big diamond respectively. Note that l can also refer to length or width or any one-dimensional unit.

For Area: A_x/A_y = (l_x/l_y)^2

Since the question states that 9:49 refers to the ratio of the area,

9/49 = (l_x/l_y)^2
l_x/l_y = sqrt{9/49} = 3/7

And as already mentioned, in the strange world of Similarities, the price IS the volume (not sure about this in the real world though :P )

So for volume: V_x/V_y = (l_x/l_y)^3

From above you already have l_x/l_y = 3/7
So V_x/V_y = (3/7)^3

Now Ah Beng's small diamond (Vx) costs $1000, which means Miss Loi's the tutor's humongous diamond (Vy) costs:

V_y = 1000/{(3/7)^3}
= $12704 (correct to the nearest dollar)!!!

Scary isn't it? But then that's only what the Ah Beng calculated with his new-found math skills ... once again things are always a bit different in the real world - Miss Loi's may be too 'calculative' to wear that ... but on the other hand, if it's free ... *drools*

2) eh tis question is a tad queer? volume ratio is 27/343 thus 343/27 x 1000 = 12703.7 thats kinda weird-.-" i DOUBT miss loi would wear a piece of metal with a rock tt cost that much >.>
