The sum of Tina and Tuffy age is equals thrice their Mather's age. Tina is 2 years younger than Tuffy. If the age of mother is 42, find the difference between age of mother and elder child.

Taffy=x elder child

Tina =x-2 younger child

Given condition:

3(Tuffy+Tina)=Mother

3(x-2+x)=42

6x-6=42

6x=48

x=8

Tina =6

Tuffy=8

B is the son of C but C is not mother of B means C is a father of B. A is married to C means A is mother of B. F is brother of B means F is son of A and C. D is daughter of A means D is daughter A and C. E is brother of C who is father of D. So E, is uncle of D..

There are 6 person A, B, C, D, E and F. C is the sister of F. B is the brother of E' husband. D is the father of A and grandfather of F. There are two fathers, three brothers and a mother in the group.

How is F related to E?

D is father of A and grandfather of F. So, A is father of F. Thus, D and A are the two fathers. C is the sister of F. So, C is the daughter of A . Since there is only one mother ,it is evident that We is the wife of A and hence the mother of C and C and F. So, B is brother of A . There are three brothers. So, F is the brother of C. Clearly, F is the son of A..

A + B means A is the father of B.

A- B means A is the wife of B.

A x B means A is the brother of B.

AÃ·B means A is the daughter of B.

If P Ã·R + Q, which of the following is true?

PÃ· R+ Q means P is the daughter of R who is the father of Q .i.e p is the sister of Q..

A + B means A is the father of B.

A -B means A is the wife of B.

A x B means A is the brother of B.

A Ã·B means A is a daughter of B.

If p x R - Q which of the following is true?

P x R-Q means P is the brother of R who is the wife of Q i.e. p is a brother in law of your Q..

The present age of three brothers are in proportion 3:4:5. After five years , the sum of their ages 75. Find their ages after 5 years (in years).

Let the present ages be 3x,4x and 5x years respectively.

Then, (3x+5)+(4x+5)+(5x+5)=75

12x=60

x=5

So, after five years their ages 20 years,25 years, 30 years respectively.

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.
