In following questions, a sequence of groups of alphabets and numbers is provided with one term missing , Choose the missing term from options. J2Z, K4X, 17V, ?, H16R, M22P

The first letters in odd numbered terms from series J, I, H and in even numbered terms from the series K, L, M. The sequence followed by the numbers is + 2, + 3, + 4, + 5, + 6. The third letter of each term is moved two steps backward to obtain the third letter of the next term.

In following alphabet series , one term missing as shown by question mark . Choose missing term from options.

AZ, CX, FU, ?

The first letter of the first, second, third, .... terms are respectively moved two, three, four, ... steps forward to obtain the first letter of the successive term. The second letter of the first, second, third.... terms are respectively moved two, three, four, ... steps backward to obtain the second letter of the successive terms.

In my row in the theatre the seats are numbered consecutively from T1 to T50. I am sitting in seat T17 and you are sitting in seat T39. How many seats are there between us?

The seats between us are numbered from T18 up to T38. So the seats between us are the 38 seats from T1 up to T38, other than the 17 seats from T1 up to T17. So there are 38 âˆ’ 17 = 21 seats.

A person's travel at a speed of 60 km per hour. Then how many metres can he travel in 5 minutes?

The speed is 60 km per hour.

The distance covered in 1 hour= 6000 m

That is the distance covered in 60 minutes=60000/60=1000 m

Then, the distance covered in 5 minutes is

=1000*5

=5000 m

.
Two person A & B removed from P to Q which are at a distance of 15 kilometres at 6 and 9 km respectively.B reacges Q and immediately return and met A at R. Find distance from P to R.

Total distance travelled by both=30

Ratio of speed= 9 :3

PR= 2/2+3*30=12 km

.
A car travel first half distance between two places with a speed of 40 km per hour and the rest of half distance with the 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)/40+(s/2)/60

=5s/240

Average speed,

=s/(5s/240)

=s*(240/5s)

=48 km/ hr

A 1000 m long train crosses a platform 100 seconds while it crosses a single pole in 20 seconds. What is the length of platforms?

Speed=1000/20

Speed=500m/s

Let the length of platform be x metres

Then,(x+1000)/100=500

X+1000=500*100

X+1000=50000

X=50000-1000

X=4900 m

There are six children playing football namely A, B, C, D, E and F.

A and E are brothers. F is the sister of E. C is the only son of A's uncle.

B and D are the daughters of the brother of C's father

How is C related to F?

F is E's and hence A's sister.

So, C is also the son of F's uncle and is, therefore, F's cousin.

So, the answer is (a).
