There are 6 persons 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. Who is E' husband?

D is father of A and grandfather of F. So, A is father of F. Thus, D andbA 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 E 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, A is E's husband..

Two bus tickets from city A to B and three tickets from city A to C cost Rs. 77 but three tickets from city A to B and two tickets from city A to C cost Rs. 73. What are the fares for cities B and C from A ?

Let Rs. x be the fare of city B from city A and Rs. y be the fare of city C from city A.

Then, 2x + 3y = 77 ...(i) and

3x + 2y = 73 ...(ii)

Multiplying (i) by 3 and (ii) by 2 and subtracting, we get: 5y = 85 or y = 17.

Putting y = 17 in (i), we get: x = 13.

the ages of two person differ by 12 years. 6 years ago the elder one was 3 years as old as younger one. What is the present age of elder person ?

Let age of elder person=x

Age of younger person =x-12

(x-6)=3(x-12-6)

(x-6)=3x-54

-6+54=3x-x

48=2x

x=48/2

24

The sum of Tony and Teddy age is thrice their mother age . Tony is two years younger than Teddy if the age of mother is 42 . Find the difference between mother and younger son.

Teddy=x elder son

Tony=x-2 younger sonGiven condition

3(Tony+Teddy)=Mother

3(x-2+x)=42

6x-6=42

6x=48

X=8

Tony = 6

Teddy=8
