Find the value of A,B,C and D

A. A = 3.5, B = 4.5, C = 9.5, D = 3.5

B. A = 2.5, B = 1.5, C = 9.5, D = 4.5

C. A = 4.5, B = 5.5, C = 9.5, D = 2.5

D. A = 5.5, B = 6.5, C = 6.5, D = 8.5

Answer: Option A

Solution(By Examveda Team)

In Give Question,
A + B = 8 ---- (i)
A + C =13 -----(ii)
B + D = 8 ----(iii)
C - D = 6 ----(iv)
Therefore equation (i) and (iii) are equal
A + B = B + D
=> A = D
Therefore, equation (iv) can be C - A = 6 ----- (v)
Now solving equation (ii) and (v), We Get C = 9.5 and A = 3.5
Put this value of A in equation in (i) B = 4.5 and value of C in equation (iv) we get D = 3.5

A = 3.5
B = 4.5
C = 9.5
D = 3.5
