Quantitative Aptitude: Problems on Ages Set 13

  1. Rashi is as much younger than Shivani as he is older than Simran. If the sum of the ages of Shivani and Simran is 60 years, what is the difference between Shivani and Rashi’s age?
    10 years
    12 years
    15 years
    14 years
    Cannot be determined
    Option E
    Shivani’s age – Rashis age = Rashi’s age – Simran’s age
    Simran’s age + Shivani’s age = 2 Rashi’s age
    Shivani’s age + Simran’s age = 60
    Rashi’s age = 30;
    Therefore,We can not find the difference between Shivani and Rashi’s age

     

  2. Abhishek got married 6 years ago. His present age is 5/4 times his age at the time of his marriage. Abhishek’s brother was 5 years younger to him at the time of his marriage. What is the present age of Abhishek’s brother?
    15 years
    25 years
    20 years
    Cannot be determined
    None of these
    Option B
    Present age of Abhishek = p ;
    Present age of Abhishek’s sister = q ;
    p = (p-6)(5/4)
    p = 30
    Present age of Abhishek’s brother = 30 – 5 = 25 years

     

  3. Simran age is 125% of what it was ten years ago, but 250/3% of what it will be after ten years. What is the present age of Simran?
    45 years
    40 years
    50 years
    55 years
    None of these
    Option C
    Simran’s age before 10 years = p
    125p/100 = p+ 10
    125p = 100p + 1000 = p = 40
    Present age = p + 10 = 50 years

     

  4. Mr. Shivam has three daughters namely Rinki, Akansha and Kavya. Rinki is the eldest daughter of Mr. Shivam while Kavya 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 Rinki after two years?
    9 years
    12 years
    18 years
    10 years
    None of these
    Option C
    Square numbers =p,q,r
    (p + 5) + (q + 5)+ (r + 5) = 44 years
    p + q + q = 44 – 15 = 29 years
    Possible values of p,q,r= 4, 9, 16 [Out of 1, 4, 9, 16, 25]Rinki’s present age = 16;
    after two years = 18 years

    Total family members = 10 + p
    25(10 + p) = 30p + 10*20
    =250 + 25q = 30p + 200
    = 5q = 50
    p = 10

     

  8. The average score of Virat Kohli after 48 innings is 49 and in 49th innings Virat Kohli scored 98 runs. In the 50th innings the minimum number of runs required to increase his average score by 2 than it was before 50th innings?

    Jaya’ father present age = x
    Jaya’ age = 2/7 x
    Jaya’ brother age = 2/7 x + 3
    x/(2/7x + 3) = 14/5
    x = 42
    Jaya’ age = 2/7 x = 2/7 * 42 = 12 years
