how many triangles are there in this picture
How?
Lets count…
Assuming smallest side of a triangle is 1 cms.
Number of triangles with side 1 cms: 12(1 + 5 + 5 +1)
Number of triangles with side 2 cms: 6(1 + 2(triangles facing upward), 1+2(triangles facing downward))
Number of triangles with side 3 cms: 2(1 triangle facing upward and 1 facing downwards).
Thus, total number of triangles are 20.

Logo Quiz 11
At a party, everyone shook hands with everybody else. There were 66 handshakes. How many people were at the party?
See Solution: How many people in party?
So total handshakes will be = (n-1) + (n-2) + (n-3) +…… 0;
= (n-1)*(n-1+1)/2 = (n-1)*n/2 = 66
= n^2 -n = 132
=(n-12)(n+11) = 0;
= n = 12 OR n =-11
-11 is ruled out so the answer is 12 persons.

how many squares are in this picture
How?
Let’s assume the smallest square side is 0.5cm in length.
Now count the squares with different length :-
0.5cm : 8
1cm : 16 +2(in the middle)
2cm : 9
3cm : 4
4cm : 1
————
Total : 40
how many squares in this picture
Lets count…
Squares with side length equal to 1 matchstick: 9
Squares with side length equal to 2 matchsticks: 5(2+1+2)
Square with side length equal to 3 matchsticks: 1 (This is difficult to find, and easy to miss)
Square with side length equal to 4 matchsticks: 1 (Everybody knows)
So total number of squares : 16

There are 3 bulbs(B1, B2 and B3) in a room on 1st floor, they can be operated using 3 switches(S1, S2, S3) present on the ground floor. You don’t know which Switch is for which bulb. How can you figure out, which switch is for which bulb if you are allowed to visit 1st floor only once.
Think before you give up, its really possible.
See Solution : 3 bulbs and 3 switchesYou have three bags and three labels. One bag has only red balls, one has only blue balls and one has both red and blue balls. Three labels are R, B and RB. R label was meant for the bag with only red balls, B label was meant for the bag with only blue balls and RB for the bag with both red and blue balls. Ram by mistake labelled the bags wrongly such that all the labels are wrong, how many minimum number of balls he should pick and from what bags to correct the labels? It is given that each bag has unlimited number of balls to be picked.
See Solution : Red and blue ballsHow ?
As the label of all the bags are wrong, bag with label RB can either have all red balls or all blue balls.
Now ram will either get red ball or the blue ball.
Case 1: Ram gets the red ball
Bag with label RB is the bag with all the red balls(R).
Bag with label B can either be RB or R(as all the labels are wrong) but as we already know R bag so it can only be RB.
We know 2 bags correctly so third bag with label R should be B.
Case 2: Ram gets the blue ball
Bag with label RB is the bag with all the blue balls(B).
Bag with label R can either be B or RB(as all the labels are wrong) but as we already know B bag so it can only be RB.
we know 2 bags correctly so third bag with label B should be R.
