Intelligence And Critical Reasoning | Alphabetical And Numerical Series

Q. No. 19:	Identify, which number is wrong in the given series : 3, 4, 10, 32, 136, 685, 4116.
A :	136
B :	10
C :	4116
D :	32

Solution Answer: D 3 * 1 +1 = 4 4* 2 +2 = 10 103 + 3 = 33 334 + 4 = 136 136*5 + 5 = 685...Ans so on. So, 32 is out of place and must be replaced by 33.

Q. No. 20:	Identify, which number is wrong in the given series : 69, 55, 26, 13, 5
A :	26
B :	13
C :	5
D :	55

Solution Answer: C 69 = 6 * 9 + 1 = 55 55 = 55 + 1 = 26 26 = 26 +1 = 13 13 = 1*3 +1 = 4 Thus, 5 does not fit in the series and should be replaced by 4.

Q. No. 21:	Choose the missing term(s) out of the given alternatives : A, Z, X, B, V, T, C , R , (..?..), (..?..).
A :	P, D
B :	E, O
C :	Q, E
D :	O, Q

Solution Answer: A A +1 = B (4th term); B + 1 = C (7th term); C +1 = D (10th term) Z-3 =V (5th term); V -3 = R(8th term) X -4 = T (6th term); T -4 = P (9th term)

Q. No. 22:	Choose the missing term(s) out of the given alternatives : eac, gce, ieg, (..?..)
A :	ihi
B :	igi
C :	kgi
D :	khi

Solution Answer: C e+2 =g; g+2 = i; i+2 = k a+2 =c; c+2 = e; e+2 = g c+2 =e; e+2 = g; g+2 = i

Q. No. 23:	Choose the missing term(s) out of the given alternatives : deb, ijg, nol, (..?..), xyv
A :	rsp
B :	stp
C :	rsq
D :	stq

Solution Answer: D d+5 = i; i+5 = n; n+5 = s; s+5 = x e+5 =j; j+5 = o; o+5 = t; t+5 =y b+5 = g; g+5 = l; l+5 =q ; q+5 = v

Q. No. 24:	Choose the missing term(s) out of the given alternatives : P3C, R5F, T8I, V12L, (..?..)
A :	Y17O
B :	X17O
C :	X17O
D :	X16O

Solution Answer: C The first letter of each triplet moves +2 steps in alphabetical order, the number in the middle moves +2, +3, +4, +5 steps in numerical order and the last letter moves +3 steps in alphabet.
