About today's teaser,

how is |f(x)= x3+y3

Teaser Question

If f(x) = x2 + y2; g(x) = xy and h(x) = x+y, then which of the following equals |f(x)|?

Choose the correct answer option:

1. g(x)[{h(x)}² – 2f(x)]
2. {f(x)}^1/3 [g(x) – h(x)]
3. h(x) [{h(x)}2 – 3g(x)]
4. g(x)[f(x) – {h(x)}³]
5. none of these

Solution

Correct Answer: 3

Explanation: x³+ y³= (x+y)³– 3xy(x+y) = (x+y) [(x+y)²– 3xy].

Teaser Question

E,
F, G, H and K are friends. Among them any one thinner than E is thinner
than G. Any one stouter than F is stouter than H. someone in the group
who is Leaner than E is not leaner than F. H is stouter than either G
or K ( but not both). Not two in the group are equally stout. The
stoutest is.

Choose the correct answer option:

1. E

2. K

3. G

4. H

5. F

Solution

Correct Answer: 5

Explanation:
Among them any one thinner than E is thinner than G means E is thinner than G.

Any one stouter than F is stouter than H means F is stouter than H.

someone in the group who is Leaner than E is not leaner than F means E is leaner than F

So, Both G and F are stouter than E. Also F is Stouter than H

H is stouter than G or K, so K is the thinnest. ( One person is thinner than E)

So the order is K E G H F

Hence the stoutest is F.

---------------------------------------------------------------------------------------------------

But:
Lets say, based on the 1st and 2nd arguments we get the follwing order in increasing order of stoutness.

H<F and E<G

3rd: someone in the group who is Leaner than E is not leaner than F means E is leaner than F

let the someone be x.
cond satisfied wen F<x<E => x is leaner thn E but not leaner thn F.
From this how can the conclusion be E<F ... ???

If we continue with F<E as i assume, then the order is H<F<E<G and there is a place for K somewhere in between all 4.
And K may be between E n F coz the cond says someone must be leaner thn E but not F.
So H<F<K<E<G.

4th: H is stouter than either G
or K ( but not both).

This cond doesnt fit in.. :( :( something is wrong.

If we continue with E<F, n follow the solution given , we arrive at K E G H F.
But this does not satisfy the cond : "H is stouter than either G
or K ( but not both)." :( :(
so somethng is wrong with the Q ...
===========================================================
is tht rite??

If x + y + z = 21, then the maximum value of (x – 6)(y + 7) (z – 4) is:
in this question how do you reach at the conclusion that :

(x – 6)(y + 7)(z – 4) will be maximum only when

(x – 6) = (y + 7) = (z – 4) = k (say) for a given value of (x + y + z) = 21

i did not get it.
i mean it can also happen that ano is greater than the other
