John decided to cycle his to his friends house at a speed of 5 kilometre per hour and the journey took 2 hour.

After the first hour John has cycle 5 kilometre

After 2 hours John has cycled 10 kilometre

Using formula of distance=speed x time, this would be calculated as:

Distance= 5*2=10 km.

A number was divided successively in order by 4, 5 and 6. The remainders were respectively 2, 3 and 4. The number is:

4 | x z = 6 x 1 + 4 = 10

5 | y -2 y = 5 x z + 3 = 5 x 10 + 3 = 53

6 | z - 3 x = 4 x y + 2 = 4 x 53 + 2 = 214

| 1 - 4

Hence, required number = 214.

A family consists of six members P, Q, R, S, T and U. There are two married couples. Q is a doctor and the father of T. U is grandfather of R and is a contractor. S is grandmother of T and is a housewife. There is one doctor, one contractor, one nurse, one housewife and two students in the family. Who is the sister of T?

Option (A)

Q, the Doctor, is the father of T. S, the Housewife, is the grandmother of T and hence the mother of Q. Since there are only two married couples one being that of Q, the grandfather of R i.e., U must be married to S. Thus, R and T will be both children of Q and these must be the students. So, P, who remains, shall be the wife of Q and she alone can be the nurse. Thus, U must be the contractor.

Clearly, R and T are children of same parents. So, R will be the sister of T.

What is the unit digit in(795 - 358)?

Unit digit in 795 = Unit digit in [(74)23 x 73]

= Unit digit in [(Unit digit in(2401))23 x (343)]

= Unit digit in (123 x 343)

= Unit digit in (343)

= 3

Unit digit in 358 = Unit digit in [(34)14 x 32]

= Unit digit in [Unit digit in (81)14 x 32]

= Unit digit in [(1)14 x 32]

= Unit digit in (1 x 9)

= Unit digit in (9)

= 9

Unit digit in (795 - 358) = Unit digit in (343 - 9) = Unit digit in (334) = 4.

So, Option B is the answer.
