Check your answer:-
Top Left Box
| 3.5 | + | 4.5 | = | 8 |
| + | + | |||
| 9.5 | – | 3.5 | = | 6 |
| || | || | |||
| 13 | 8 |
Explanation:
We can make four equations
A+B = 8
C-D = 6
A+C = 13
B+D = 8
now we have four variables with four equations so it should be easy to solve. let’s solve these four equations
if we add the four equations
A+B+C-D+A+C+B+D = 8 + 6 + 13 + 8
2(A+B) + 2C = 35
2C = 35 – 2*8 —- by replacing A+B
2C = 35 – 16 = 19
C = 9.5
from 2nd Equation C – D = 6
D = C – 6
D = 9.5 – 6
D = 3.5
from 3rd equation
A+C = 13
A = 13 – C
A = 13 – 9.5
A = 3.5
from 4th equation
B + D = 8
B = 8 – D
B = 8 – 3.5
B = 4.5
If February=June,
January=April,
September=September,
and August=April…
then what is March?
IF,
9 = 100,
8 = 143,
7 = 162,
6 = 165,
Then,
5 = ?
If 1 + 2 = 13
2 + 3 = 61
3 + 4 = 193
Then 4 +5 = ?
Check your answer:-
A+B = (A*B + 2)^2 – 3

What’s the missing number?
Can you find the missing number in the below triangle from the 4 options given in the image ?
Check your answer:-
Answer With ExplanationExplanation: Its actually simple logic, generally we think to find out the relation between the opposite sides, but here the relation is in between adjacent numbers, which is very unusual though.
9 * 2 = 18 -1 = 17
160 *2 = 320 -1 = 319
475 * 2 = 950 – 1 = 949
4, 72, 652, ?
Check your answer:-

3^3 => 27 => reverse 72
4^4 => 256 => reverse 652
thus the next number should be
