1. The average runs scored by a cricketer is 42 innings, is 40. The difference between his maximum and minimum scores in an inning is 100. If these two innings are not taken into consideration, then the average score of remaining 40 inning is 37. Calculate the maximum runs scored by him in an innings?
   A. 125
   B. 150
   C. 110
   D. 100
   E. None of these
   
   Answer & Explanation

   Answer – B. 150
   Explanation :
   Let the minimum score = x
   ∴ Maximum score = x + 100
   ∴ x + (x + 100) = 42 x 40 – 40 x 37
   ⇒ 2x + 100 = 1680 – 1480 = 200
   ⇒ 2x = 200 – 100 = 100
   ⇒ x = 50
   Maximum score = x + 100 = 50 + 100 = 150
   
   
2. Silvia was married 8 year ago. Today her age is 9/7 times to that time of marriage. At present his son’s age is 1/6th of her age. What was her son’s age 3 year ago?
   A. 4 yr
   B. 2 yr
   C. 3 yr
   D. 5 yr
   E. None of the Above
   
   Answer & Explanation

   Answer –B. 2 yr
   Explanation :
   Silvia’s age 8 year ago = x
   Present age = x + 8
   x + 8 = 9/7 x
   7(x + 8)= 9x
   x = 28; 28 + 8 = 36
   Son’s age = 1/6 * 36 = 6
   Son’s age 4 year ago = 6-4 =2
   
   
3. Eight years ago, Pavi’s age was equal to the sum of the present ages of her one son and one daughter. Five years hence, the respective ratio between the ages of her daughter and her son that time will be 7:6. If Pavi’s husband is 7 years elder to her and his present age is three times the present age of their son, what is the present age of the daughter?
   A. 15 years
   B. 23 years
   C. 19 years
   D. 27 years
   E. 13 years
   
   Answer & Explanation

   Answer – B. 23 years
   Explanation :
   P – 8 = S + D —(1)
   6D + 30 = 7S + 35 —(2)
   H = 7 + P
   H = 3S
   3S = 7 + P —-(3)
   Solving eqn (1),(2) and (3) D = 23
   
   
4. Ravi’s present age is three times his son’s present age and 4/5th of his father’s present age. The average of the present ages of all of them is 62 years. What is the difference between the Ravi’s son’s present age and Ravi’s father’s present age?
   A. 62 years
   B. 64 years
   C. 69 years
   D. 67 years
   E. 66 years
   
   Answer & Explanation

   Answer – E. 66 years
   Explanation :
   Present age of Ravi is = 4/5x
   Present age of Ravi’s father is = 4/15x
   Ratio = 15: 12 : 4
   Difference between the Ravi’s son’s present age and Ravi’s father’s present age = 62/31 * 3(15 – 4).
   = 2*3*11 = 66 year.
   
   
5. The respective ratio between the present age of Mary and Deepa is x : 42. Mary is 8 years younger than Prema. Prema’s age after 8 years will be 33 years. The difference between Deepa’s and Mary’s age is same as the present age of Prema. What is the value of x?
   A. 18
   B. 10
   C. 16
   D. 11
   E. 17
   
   Answer & Explanation

   Answer – E. 17
   Explanation :
   Prema’s age after 8 years = 33 years
   Prema’s present age = 33 – 8= 25 years
   Mary’s present age = 25 – 8 = 17 years
   Deepa’s present age = 17 + 25 = 42 years
   Ratio between Mary and Deepa = 17 : 42
   X = 17
   
   
6. Mr. Sharma has three sons namely Ram, Amit and Karan. Ram is the eldest son of Mr. Sharma while Karan is the youngest one. The present ages of all three of them are square numbers. The sum of their ages after 5 years is 44. What is the age of Ram after three years?

   B. 13 years
   C. 19 years
   D. 17 years
   E. 16 years
   
   Answer & Explanation

   Answer – C. 19 years
   Explanation :
   Square numbers – x, y, z
   (x + 5) + (y + 5)+ (z + 5) = 44
   x + y + z = 44 – 15 = 29
   Possible values of x, y, z = 4, 9, 16 [Out of 1, 4, 9, 16, 25]
   Ram’s present age = 16; after three years = 19

   B. 9 : 4
   C. 5 : 1
   D. 7 : 2
   E. None of the Above
   
   Answer & Explanation

   Answer – C. 5 : 1
   Explanation :
   Ages of Reshma and her daughter = 6x, x
   [6x + 1 + 6] – [x + 1 + 6] = 20
   5x = 20; x = 4
   Ratio = 6x + 1 : x + 1 = 25 : 5 = 5:1

9. Ravi is as much younger than Surya as he is older than Suresh. If the sum of the ages of Surya and Suresh is 50 years, what is definitely the difference between Surya and Ravi’s age?
   A. 12 years
   B. 23 years
   C. 19 years
   D. 27 years
   E. Can not be determined
   
   Answer & Explanation

   Answer – E. Can not be determined
   Explanation :
   Surya’s age – Ravi’s age = Ravi’s age – Surya’s age
   Suresh’s age + Surya’s age = 2 Ravi’s age
   Surya’s age + Suresh’s age = 50
   Ravi’s age = 25; We can not find the difference between Surya and Ravi’s age
   
   
10. Amit’s present age is 1.5 times of Hari’s present age. If after 4 years, Amit’s age will be twice of Hari’s age 4 years ago. What is the sum of the present ages of Amit and Hari?
    A. 52 years
    B. 53 years
    C. 60 years
    D. 67 years
    E. 63 years
    
    Answer & Explanation

    Answer – C. 60 years
    Explanation :
    A = 1.5 * H
    A + 4 = 2 * (H – 4)
    A + 4 = 2H – 8
    A + 12 = 2H
    1.5H + 12 = 2H
    H = 24
    A = 24 * 1.5 = 36
    Sum = 36 + 24 = 60
