Can you solve the below maths equation problem by replacing the question mark with the correct number?
Note: It has more than one solution.
40 or 96
Explanation:
Solution A :
Add the rhs of the last line to the current line
1 + 4 = 5
5 + 2 + 5 = 12
12 + 3 + 6 = 21
21 + 8 + 11 = 40
Solution B :
RHS = 1ST NUMBER + (1ST NUMBER * 2ND NUMBER)
1 + (1 x 4) = 5
2 + (2 x 5) = 12
3 + (3 x 6) = 21
8 + (8 x 11) = 96

A small media company got 20 employees.
The employee consists of reporters, camera-man and the writers
Every reporter earns daily $3, camera-man 1.5$ and writers earn 0.5$
How many reporters, camera-man and the writers are there?
reporters=2, camera-man=5 and the writers=13
Let the number of reporters, camera-man, and writers are denoted by r, c, and m respectively.
From the given information we can write the following 2 equations;
r + c + m = 20 . . . . . . (1)
3r + 1.5c + 0.5m = 20 . . . . . (2)
Multiplying equation (2) by 2 we get;
6r + 3c + m = 40 . . . . . (2)
equation3 - equation 1
5r + 2c = 20
The unique solution with whole numbers is r = 2 & c = 5
Therefore from equation(1) we can find;
m = 13
=> reporters=2, camera-man=5 and the writers=13
In a word of riddles called Briddles, 9 numbers from 1 - 9 want to reach to the other side of the river. Since its a world of riddles, therefore, there are some rules:
Rule-1: Maximum 3 numbers can cross at a time.
Rule-2: River cannot sail on its own.
Rule-3: The sum of numbers crossing at a time must be a square number.
You need to plan trips such that minimum trips are needed for all numbers to cross.
7 Trips
Send 2+5+9 = 16
Bring back 9
Send 3+4+9 = 16
Bring back 9
Send 1+7+8 = 16
Bring back 1
Send 1+6+9 = 16

Can you determine the height of red bar with the help of information provided in the picture below?
8m
From green bar, we can deduce that
the height of vertical bar = 2/3 of uninterrupted shadow length of the bar.
Therefore shadow of 6m of red bar indicates the height of 4m.
The remaining red bar casts a direct 1:1 vertical projection on the wall.
Therefore total length = 4m + 4m = 8m.
Can you replace each alphabet with the number (1 - 9) to make below equation correct ?
AB * C = DE - F = GH / I
39 * 1 = 45 - 6 = 78 / 2
AB - C = DE / F = GH * I can be solved as
A = 3
B = 9
C = 1
D = 4
E = 5
F = 6
G = 7
H = 8
I = 2
So below equation can be solved as:
AB - C = DE / F = GH * I
39 * 1 = 45 - 6 = 78/2
39 = 39 = 39.

In the attached picture, you will find a pyramid formation, that is made up of ten circles. If you can move only 3 circles, can you turn it upside down?We have numbered the coins so that you can comment the numbers as answers.
If you move the circles 1, 7 and 10 as shown in the image, you can turn it upside down.
In a certain bank, a man deposits a certain amount. According to the bank policies, the amount will get doubled up in a year but as the service charge, they will also deduct Rs. 65 by the end of every year.
If after the 6th year, the amount becomes 0, what do you think is the original amount he deposited in the bank?
This is totally impossible in real because you do not pay in bank in fractions. However, the only possible answer is explained below:
Year Amount Interest and Deduction
Start 63.984375
Y1 End 62.968750 63.984375 * 2 - 65
Y2 End 60.937500 62.96875* 2 - 65
Y3 End 56.875000 60.9375 * 2 - 65
Y4 End 48.750000 56.875 * 2 - 65
Y5 End 32.500000 48.75 * 2 - 65
Y6 End 0.000000 32.5 * 2 - 65 = 0
