## Question 1

Two boys are playing on a ground. Both the boys are less than 10 years old. Age of the younger boy is equal to the cube root of the product of the age of the two boys. If we place the digit representing the age of the younger boy to the left of the digit representing the age of the elder boy , we get the age of the father of the younger boy. Similarly, if we place the digit representing the age of the elder boy to the left of the digit representing the age of the younger boy and divide the figure by 2, we get the age of the mother of the younger boy. The mother of the younger boy is younger to his father by 3 years.

## Answers with Solution

#### 1)( c) is the right answer.

Only two combinations are possibleYounger Older

2 4

3 9

Cubes of natural number are 1, 8, 27, 64 ….. Here, 64 and above is not possible as the age will go above 10. only (b ) and (c ) satisfies the case of mother and father.

#### 2) (a) is the correct answer

→ Total seats in the hall = 200→ Seats vacant =20

→ Total waiting =180

→ Ladies = 72

→ Seating capacity of flight = 2/3 *180 =120

→ Number of people in Flight A = 100 for Flight B = 180 – 100 = 80

→ Thus ,number of air hostess for A= 4

→ Empty seats in the flight B = 120-80 = 40

→ 40 : 4 = 10:1

#### 3) (D) is the correct answer

→ Option (c ) is ruled out by statement (vii)→ Option (a)is ruled by statement (vii) and (viii)

→ From statement (iv) , S had Rs. 30 to start and D Rs. 20

→ From statement (ii), option B is not possible as S was left with Rs. 1 , he spent Rs. 29 but according to the (b) he spent Rs. 1.50 more than D.But D had only Rs. 20 Hence option (D) is correct.
