Q. If A7C, B13E, C4H, then B ? D (āĻ¯āĻĻāĻŋ A7C, B13E, C4H āĻšāĻ¯āĻŧ, āĻ¤ā§āĻ¨ā§āĻ¤ā§
B ? D
Options / āĻŦāĻŋāĻāĻ˛ā§āĻĒāĻ¸āĻŽā§āĻš: (A) 6 (B) 8 (C) 9 (D) 10
Solution / āĻ¸āĻŽāĻžāĻ§āĻžāĻ¨
Rule: (Add the positions of two letters)² → Add the digits (āĻĻā§āĻāĻž āĻāĻā§°ā§° āĻ¸ā§āĻĨāĻžāĻ¨āĻŽāĻžāĻ¨ āĻ¯ā§āĻ āĻā§°āĻŋ)² → āĻ āĻāĻ āĻ¯ā§āĻ āĻā§°āĻ
1) A7C : A = 1, C = 3
= (1 + 3)² = 4² = 16
= 1 + 6 = 7
2) B13E : B = 2, E = 5
= (2 + 5)² = 7² = 49
= 4 + 9 = 13
3) C4H : C = 3, H = 8
= (3 + 8)² = 11² = 121
= 1 + 2 + 1 = 4
Now B ? D : B = 2, D = 4
= (2 + 4)² = 6² = 36
= 3 + 6 = 9
Ans: (C) 9
