it was quiet gud. wat was the diagram in which there was 1 line of symmetry nd no rotational order.
wat was the regular figure that exactly fitted the place at B in the question abt 12 sided polygon.

 

[hashim2]

what was the answer of the upper bound question?

 

[Vogue]

what was the answer of the upper bound question?

do u remember the values?

 

[syed1995]

what was the answer of the upper bound question?

0.95

and 2.8

Kite or isosceles/right trapezium
Triangle

Kite or isosceles/right trapezium
Triangle

u mean all of those r correct: kite nd isosceles triangle nd trapezium?

 

[syed1995]

No. For the symmetry only Right/Isosceles Trapezium and Kite were correct.
But for the 12-sided polygon Triangle was correct.

 

[Vogue]

No. For the symmetry only Right/Isosceles Trapezium and Kite were correct.
But for the 12-sided polygon Triangle was correct.

oh ok!

oh and btw what was the answer to that question in which they asked to hours and mins of flight from london to chennai ??????

I think for the 1 line of symmetry and no rotational order, it can be 3 possible answers.
And for the figure that fits the point B is a equilateral triangle. Because they want a regular polygon.

 

[Shehan Livera]

What about the question about the classes. The probability question. It was a bit confusing.

The answer is 10 hours and 05 minutes

 

[Rimi]

No. For the symmetry only Right/Isosceles Trapezium and Kite were correct.
But for the 12-sided polygon Triangle was correct.

I think they'll accept only 'Equilateral Triangle' Not just 'triangle'

What about the question about the classes. The probability question. It was a bit confusing.

The answer to the probablity question was 8/15

 

[Phyecomath]

what about the sm+sn= (something/t) and find s and t. and also the Imran guy said 20min is the longest time to complete the puzzle. why is the statement wrong?

 

[Rimi]

9.55

and 2.8

wasn't it 0.95 m? I could be wrong though.

 

[Shehan Livera]

Yep. Because they have said to write a regular figure.

Don't remember the values of s adnd t correclty, but i think one was 2, and the other was -5. And I messed up the frequecy polygon question, so no cmments on that XD

 

[Shehan Livera]

wasn't it 0.95 m? I could be wrong though.

Your answer is correct. They wanted in meters. the upper bound of the length must be 0.95 therefore.

 

[Phyecomath]

i think they won't accept triangle becoz at the beginning of the question said draw a quadrilateral so it must be a kite
