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.
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
Check your answer:-
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
Check your answer:-
however you can get the value by doing
Eq3 – Eq2 + Eq1
thus the answer will be 27 – 24 + 21 => 24

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
Let’s see if you can solve this one.
What is the heigh of the table in cm?
Check your answer:-
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
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

One-tenth of the cars in a car park are yellow. Another car arrives and now one-ninth of the cars are yellow.
Check your answer:-
as yellow car’s percent increases from 1/10th to 1/9th after new car arrives, so new car must be a yellow car.
So we can form this equation
1 + x/10 = (x+1)/9
Now we just need to solve this equation
on multiplying both sides by 9*10 =>
9*10 + 9x = 10x + 10
90 – 10 = 10x – 9x
x = 80
So there were 8 yellow cars initially among a total of 80 cars(i.e. 1/10th)
and a new yellow cars comes making 9 yellow cars in total of 81 cars.(i.e. 1/9th)
So answer to the question is 81. there are a total of 81 cars now.
