Collection of Best Maths Puzzles
In this category we have mathematical puzzles which requires some kind of math to solve, like: algebra, equations, permutation and combinations.
Some of these maths puzzles are very simple and some are very hard, check these out, we are sure you will like it for sure.
Fruit puzzle
Check your answer:-
lets write the equations with shortcodes A for apple, L for lemon, W for watermelon and T for tomato
3A = 30 => A = 10
2L + A = 40 => 2L = 40 -A = 30 => L = 15
from 4th T + T^2 = 12 => T => T(1+T) = 12 => T = 3
from 3rd T + 2W => 24 => 2W = 24 – T = 21 => W = 21/2
the last one
W + L*T => 21/2 + 15*3 => 10.5 + 45 => 55.5
Maths Puzzle – 4, 4, ?
Which number should replace the question mark?
Check your answer:-
This is following this pattern
A*B – (B-A) – 1
for first line 4*6 – (6-4) -1 => 24 – 2 -1 => 21
you can see the same for all other lines, thus for the last one
4*4 – (4-4) – 1 => 15
Can you solve it in a minute?
Check your answer:-
You can not get individual item’s value as there are only 3 equations and more than 3 variables.
however you can get the value by doing
Eq3 – Eq2 + Eq1
thus the answer will be 27 – 24 + 21 => 24

Box 4 (top right)
Click here to See SolutionLet’s quickly write the equations
B1 + B2 = 14
B1 + B3 = 15
B2 + B4 = 16
B3 – B4 = 10
by adding all equations
B1 + B2 + B3 = (14 + 15 + 16 + 10 )/2 = 55/2 = 27.5
B3 = 27.5 – (B1 + B2) = 27.5 – 14 = 13.5 => B3 = 13.5
B2 = 27.5 – (B1 +B3) = 27.5 – 15 = 12.5 => B2 = 12.5
B1 = 14 – B2 = 14 – 12.5 = 1.5 => B1 = 1.5
B4 = B3 – 10 = 13.5 – 10 = 3.5 => B4 = 3.5
Find the hieght of table with Cat and tortoise
Let’s see if you can solve this one.
What is the heigh of the table in cm?
Check your answer:-
let’s assume height of the table is T and cat is C and R of tortoise.
let’s write down the equations
T + C – R = 170cm
T + R – C = 130cm
add both the equations
2T + C – R + R -C = 170 + 130 cm
2T = 300cm
T = 150cm

Glass and water puzzle, how fast can you solve it?
Check your answer:-
Lets say B is half full blue glass, Y is half full yellow glass and R is half full red glass, then
2B + B + 2B = 15 => 5B = 15 => B = 3
2Y – Y + 2B = 10 => Y + 2*3 = 10 => Y = 4
2R + 2R – R = 6 => 3R = 6 => R = 2
Now
B + (B+R)*Y = 3 + (3+2)*4 => 3 + 20 => 23
A lady walks into a store and steals $100
A lady walks into a store and steals a $100 bill from the register without the owner’s knowledge. She comes back 5 minutes later and bus $70 worth of goods with the $100 bill. The owner her $30 in change.
How much did the owner loose?
Check your answer:-
how many 9s ?
Let me see how clever everyone is…
Solve the riddle :
Write numbers from 1 to 100…. how many 9s do you see?
Think properly and then answer
Check your answer:-
one 9 in every 10s (like 9, 19, 29, etc) => 10
extra 10 9s in 90 – 99 => 10
thus total 20
extra 10 9s in 90 – 99 => 10
thus total 20
