Answer: 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

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.

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.

X%y = X*y/100 = (200/y)*(y/100) = 2

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.

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.

Answer: 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.

Answer: 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

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

Thus TRIP =

Lets draw the diagram first

From above diagram we can write this equation

x+10 + x = 40 => 2x = 30 => x = 15

thus distance between 1st and 4th mansion is 60 + x = 75 km
