Which term comes next in the series : YEB, WFD, UHG, SKI ?

Clearly, the first letter of each term is moved two steps backward to obtain the first letter of the next term. So, the first letter of the missing term will be Q. The second letter of the first, second, third, fourth terms are respectively moved one, two, three and four steps forward to obtine the corresponding letter of the subsequent term. So, the second letter in the missing term

will be O. The third letter is alternately moved two and three steps forward to obtain the corresponding letter of the subsequent term. So, the third letter in the missing term will be L. Thus, the missing term is QOL. Hence, the answer is (a).The third letters of the first, second, third, fourth and fifth terms are moved seven, eight, nine, ten and eleven steps forward respectively to obtain the third letter of the successive terms. Thus, the missing term would be ZKW. Hence, the answer is (a).

Jimmy bought 60 Mangoes and 40 Apples. He found 30% of Mangoes and 10% of apples were overripe. Find the number of fruit in good condition.

Total fruit = 60 + 40 = 100

Overripe Mangoes = 30% of 60

= 30/100 x 60

=18

Overripe Apples = 10% of 40

= 10/100 x 40

=4

Total number of overripe fruit= 18+4=22

Therefore Number of fruit in good condition= 100-22= 78

In following number series, either one term is missing or is incorrect.

Choose correct answer from options 1, 5, 11, 19, 29, 55

Choose correct answer from options 1, 5, 11, 19, 29, 55

The correct sequence is + 4, + 6, + 8, + 10, ....

So, next term after 29 = 29 + 12 = 41.

The term after 41 will then be (41 + 14) i.e. 55.

41 is missing..

In following number series, two terms have been put within brackets. Choose the appropriate option

Choose the appropriate option 2, 3, (6), 11, 18, (30), 38

Choose the appropriate option 2, 3, (6), 11, 18, (30), 38

The correct sequence is + 1, + 3, + 5, + 7, + 9, + 11.

Clearly, the term 6 is correct,

But, 30 is wrong and should be replaced by (18 + 9) i.e. 27.
