.
Which term will replace the question mark in the series :

ABD, DGK, HMS, MTB, SBL, ?

A car travels first half distance between two places with a speed of 40 kilometre per hour and rest of half distance with a speed of 60 km per hour. The average speed of car is:

Let the total distance covered be"s" km.

Total time taken,

=(s/2)/30+(s/2)/60

=3s/120

Average speed,

=s/(3s/120)

=s(120/3s)

=40 km/hr

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

Choose the appropriate option 3, 10, 29, (66), (127), 218

Choose the appropriate option 3, 10, 29, (66), (127), 218

The sequence is 1

Clearly, both the terms 66 and 127 are correct..

ABD, DGK, HMS, MTB, SBL, ?

Clearly, the first letters of the first, second, third, fourth and fifth terms are moved three, four, five, six and seven steps forward respectively to obtain the first letter of the successive terms.

The second letters of the first, second, third, fourth and fifth terms are moved five, six, seven, eight and nine steps forward respectively to obtain the second letter of the successive terms.

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)..
