I thought of
providing some stuff for students studying in the range 5th to 10th
standard. This stuff is a combination of two sets. One is Math&Logic based
and the other is Knowledge based. This stuff is a mix of some questions that
are based on math fundamental concepts and remaining questions that are based
on commonsensical and out-of-box thinking. These do not look like standard
questions that are given in school-level exams but mostly resemble or can act
as base for the math and logic aptitude sort of questions that are asked in
various entrance exams. My primary intention is to inculcate in kids an
interest and liking on maths. I strongly opine that math solving skills are
very much needed to excel in diverse fields of studies ranging from Science, Engineering
to Economics, Management studies etc.
To be frank
on my part, I am starting this post with small number of questions at hand but
I will try to enrich this bit bank by updating it from time to time.
Math and
Logic Based Set:
1. A number when
used in denominator results in an 'undefined' value. What's that number?
2. X is a
number. If you add X to any other number you get the other number. If you
subtract X from any other number, even then you get the other number. What is
the number X?
3. Y is a number.
If you multiply Y with any other number you get the other number. If you divide
any other number with Y, even then you get the other number. What is the number
Y?
4. It's a
geometric figure and there is one point 'X' with in that figure. All points on
that figure are equidistant from X. What is that geometric figure?What is the
point X called?

English alphabets are symmetric in shape when written in upper case? (If
bisected horizontally)

15. What is the
square of 995?
16. Ram walked 6
m Eastwards and turned 90 degrees to his left and continued to walk for 8m and
stopped there. At what distance and direction is the final point positioned
with respect to the initial point if we join the two points by a straight line?
17. Amar can do a
work in 60 days and Akbar in 90 days. In how many days both of them can jointly
do that work?
18. Anthony
started a journey by car to his home town which is 100 km away. He travels
first 40 km at a speed of 40 kmph, next 40 km at a speed of 80 kmph and the
remaining distance at a speed of 40 kmph. What is the average speed with which
he travelled to reach the destination?
19. Given the
radius of a circle is 5 cm, what is the distance between two points on the
circle which are located exactly opposite to each other?
20. “The radius
of a circular path is 7 m. If I start at a point on the path and travel 88 m
along the path, then I will reach the same point at which I have started”. Is
this statement True/False?
21. The statement
“X/X = 1” does not work when X=____
22. “Square root
of 16 is 4”- is this sentence perfectly correct?
23. “Square of 4
is 16”- is this sentence perfectly correct?
24. If I say “A/B
= C/D”, does it mean A=C and B=D?
25. If I say “A*B
= C*D”, does it mean either A=C or A=D?
26. If XY
= 0, then X must be___, irrespective of the value of Y.
27. If XY
= 1, then Y must be___, irrespective of the value of X.

5. “For a right
angle triangle if 'a' is hypotenuse and 'b' and 'c' are sides then, a2=b2+c2”
- whose theorem is this?
6. “Any three
points which are not collinear can form a triangle”. Is this statement
True/False?

angle triangle, hypotenuse is the largest side”. Is this statement True/False?
9. “In a right
angle triangle, length of hypotenuse is the greater than sum of the lengths of
other two sides”. Is this statement True/False?
10. If the length
and breadth of a rectangle are made equal, then it becomes a _____
