. In following questions, a sequence of groups of alphabets and numbers is provided with one term missing , Choose the missing term from options. LXF, MTJ, NPN, OLR, ?

The first letter of each term is moved one step forward, the second letter is moved four steps backward and the third letter is moved four steps forward to obtain the corresponding letters of the next term.

When a number is divided by 13, the remainder is 11. When the same number is divided by 17, then remainder is 9. What is the number ?

x = 13p + 11 and x = 17q + 9

13p + 11 = 17q + 9

17q - 13p = 2

q =(2 + 13p) /17

The least value of p for which q =(2 + 13p) /17is a whole number is p = 26

x = (13 x 26 + 11)

= (338 + 11)

= 349

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

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

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

In a fort there is enough food sufficient for 1200 man 5 days how long the food would have last for if there would would have been thousand men.

Let food will last for X days.

As men and days are inversely proportional to each other so

X/5=1200/1000

X=1.2*5=5

X=6
