20 ----- 25 ----- 12
8 ----- 9 ------ ?
6 ----- 6 ------ 4
a) 10 b)12 c)48 d) 4
Solution :-
Logic :- Let in column numbers as a, b , c and d,
- a - b = 4(c - d)
Explanation :-
28 - 20 - 8 - 6
→ (28 - 20) = 4(8 - 6)
→ 8 = 4 * 2
→ 8 = 8 .
similarly,
37 - 25 - 9 - 6
→ (37 - 25) = 4(9 - 6)
→ 12 = 4 * 3
→ 12 = 12 .
applying same logic in next we get,
36 - 12 - ? - 4
→ (36 - 12) = 4(? - 4)
→ 24 = 4(? - 4)
→ 6 = ? - 4
→ ? = 6 + 4
→ ? = 10 (a) (Ans.)
