Number And Letter Series - MCQ Test 1 (With Solutions) CAT, Common Admission Test - LR MCQ

The given series starts with the last 4 alphabets of the English language and then gives a break of 2 alphabets, followed by the next four alphabets and so on. Hence, the next term in the series would be H (after skipping J and I). So option (c) is the answer

Two series are intermingled with each other as 1, 3, 5, 7, 9, 11 and 2², 3², 4², 5², 6². Hence, the next term in the series would be 7² = 49, so the correct answer is option (b).

GP with common ratio 1/5. Hence, option (d) is correct.

The series follows the logic of +3, +4, +5, +6 and +7. Hence, the missing term would be 19 + 5 = 24. So option (d) is the correct answer.

The logic of this series is that the sum of two numbers makes the third one in the series. This we can observe by seeing 28+84=112, 84+112=196 and so on. The only number that does not satisfy this logic is 308 +504, which should be 812 and not 872. Thus, 872 is the wrong number in the series.

The logic of the additions are 121,171, 221, 291, 361 and so on. Thus, the number series should be 300, 421, 592, 813, 1104,1465. The number 815 is misplaced in the above series and hence Option (c) is incorrect.

5N% is the only instance of a consonant either followed by a symbol or preceded by a vowel but not both. Option (c) is correct.

EGJNS follows the skipping of 1, 2, 3 & 4 letters respectively as we can see in: EFGHIJKLMNOPQRS

For the first alphabet add 6 to the position number to get the next first alphabet of the next element of the series and for the second alphabet subtract 6 from the position and we’ll get the required number. Option (c) is correct.

It is a repetition of the string: anebb. The missing alphabets in the blanks are: bnabe. Option (c) is correct.
