Cars Math Puzzle – How many cars in the parking ?
One-tenth of the cars in a car park are yellow. Another car arrives and now one-ninth of the cars are yellow.
How many cars are now in the car park?
Check your answer:-
lets say there are total x cars, thus
x/10 number of cars are yellow initially.
x/10 number of cars are yellow initially.
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.
How many filled bottles can be collected?
A shopkeeper gives a full bottle of soft drink in return for five empty bottles. A guy has 77 empty bottles and he can use them to get full soft drink bottles.
How many filled bottles will he be able to collect?
Check your answer:-
77 empty bottles= 15 filled bottle+2 empty bottle
15+2 empty bottles=3 filled +2 empty bottles
3+2 empty bottles=1 filled bottle
i.e. total filled bottle are 15+3+1=19
15+2 empty bottles=3 filled +2 empty bottles
3+2 empty bottles=1 filled bottle
i.e. total filled bottle are 15+3+1=19
Number game – Horse + Cat + Hen ?
Check your answer:
Answer With SolutionAnswer: 88
Solution:
From Equation 1: 3Hen = 6 => 1Hen = 2
From Equation 2: Cat + Hen = 7
=> Cat = 7 – Hen = 7 – 2 = 5
From Equation 3: Horse – Cat = 76 => Horse = 76 + Cat = 76 + 5 = 81
Thus Horse + Cat + Hen = 81 + 5 + 2 = 88

Flower math puzzle
What will be the value of Yellow flower + Red flower*Blue Flower?
Check your answer:-
Answer With Explanation
Answer: 81
Explanation:
from first equation red flower = 20
from second equation blow flower = (30 – 20)/2 = 5
from third equation 5 – 2yelloflower = 3 => yello flower = (5-3)/2 = 1
Thus Yellow flower + Red flower*(Blue Flower with four petals)
yes thats the catch, blue flower with 4 petals should be of value 4
= 1 + 20 *4 = 81, remember BODMAS rule, multiplication first.
Math Puzzle – If X y =200 X-y=100 X%y=?
Can you solve this Math Equation?
If X*y =200, X-y=100 than X%y=?
Check your answer:-
Answer With Explanation
Answer: 2
Explanation:
You can solve it easily if you read the question carefully.
we want to know X%y,i.e. X percent of y and not x multiplied by y.
Explanation:
You can solve it easily if you read the question carefully.
we want to know X%y,i.e. X percent of y and not x multiplied by y.
X%y = X*y/100 = (200/y)*(y/100) = 2
How many pushups in 6 months?
If we do 1 push up repetition per day, 3 sets, then increase it by one rep per week for same three sets, how many push ups will we be doing in 6months?
Check your answer:-
Answer With Solution
Answer: 7215
Solution:
Let’s assume 30 days in a month, so 6*30 = 180 days in 6 months, i.e. 180/7 = 25weeks + 5 days.
Solution:
Let’s assume 30 days in a month, so 6*30 = 180 days in 6 months, i.e. 180/7 = 25weeks + 5 days.
number of push ups in first week 3*7 = 21
so total number of push ups in 25 weeks = 21 + 21*2 + 21*3 …. 21*25
its an arithmetic progression with a1 = 21 and d = 21
its Sum = n(a1+an)/2 = 25(21 + 21*25)/2 = 21*25*26/2 = 6825
Push ups done in 5 days = 21*26*5/7 = 26*15 = 390
Total push ups in 6 months = 6825 + 390 = 7215.
What will be Jane’s tree height puzzle
jane, ali and pat each planted a tree 90cm in height . in the time it took jane’s tree to grow by 1 cm, ali’s tree grow by 2 cm. by the time it took ali tree to grow by 2cm pat tree grow by 3 cm . how tall was jane tree when pat tree was 108 cm in height.
Check your answer:-
Answer With SolutionAnswer: 96cm
Solution: let’s say jane’s tree grow by 1cm in X time, and in the same time ali’s tree grow by 2cm and pat’s tree grow by 3cm.
so to grow 108 – 90 = 18 cm, pat’s tree should take 18/3 = 6X time and jane’s tree should grow by 6cm in the same time.
Math Puzzle – Wall Clock x Football – Table Fan = ?
One more math puzzle for you
What will be the value of (Wall Clock)x(Football) – Table Fan in the below image ?
Check your answer:-
Answer With SolutionAnswer: 4
Solution:
You might want to solve it simply like this
First equation: Football + Football + Football = 18 => Football = 18/3 = 6
Second Equation: Wall Clock= 9/3 = 3
Third Equation: Table Fan * Table Fan – Table Fan = 6 => (Table Fan) x (Table Fan – 1) = 6
from 3×2 = 6 => Table Fan = 3
Thus Wall Clock x Football – Table Fan = 3 x 6 – 3 = 15
BUT, if you look carefully, it is not a simple math equation puzzle, football in last equation is different than other, wall clock in 4th equation having different time than the ones in second equation, similarly table fan has 2 blades than 3.
So how do we solve it?
In the first equation black marks on Football are 6, therefore Football value is : 6
In the Second equation clock shows 3pm.. so clock value is 3
In the third equation, table fan has 3 blades, thus having a value of 3, OR you can say a table fan with 3 blades has value 3, thus with 2 blades should have a value 2.
In last equation clock is 2 and Football marks are 3, and table fan has 2 blades
thus 2×3 -2 = 4

Beer Bottle Burger Math Equation Puzzle
Can you tell what will be the sum of the fourth row ?
i.e. Sum of Burger + Beer Bottle * Beer Mug ?
obviously you have to apply some mathematics here, question is how fast you can solve it.
Check your answer:-
Answer: 15
Solution:
If you see there are 3 variables and 3 equations, we can solve the equations and get the variables values and than we can find the value of fourth equation.
From the first equation we can say that Beer Bottle = 10
than from the second Burger = (20 – 10)/2 = 5
and from the third equation Beer Mug = (9 – 5)/4 = 1
Thus Burger + Beer Mug * Beer Bottle = 5 + 1*10 = 15
here as per BODMAS 5 + 1*10 will be 5 + 10 and not 6*10
