Check your answer:-

Bottom Right Box

Answer With Explanation
Answer:

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

Check your answer:-

Tried enough already?
Answer With Explanation
Answer: 949

Explanation: 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
