Study the given pattern carefully and select the number that can replace the question mark (?) in it.
3 18 27
14 13 ?
136 403 468
(a) 15
(b) 19
(c) 12
(d) 13
Sol:
Pattern follows here is Sum × Digit sum
(3 + 14) × (3+1+4) = 34
(18 + 13) × (1+8+1+3) = 62
(27 + x) × (9+ Digit sum of x) = 468
By option, C
= (27 + 12) × (9+3) =39×12 = 468 Ans.
