Questions Penned by Yogit

  1. A said to B – seven years ago I was seven times as old as you were and three year hence I will be three times as old as you will be. The ages of A and B
    a) 52, 12
    b) 42, 12
    c) 32, 12
    d) 54, 14
    e) None of these
    Answer – b) 42, 12
    Explanation :
    A – 7 = 7*(B – 7)…….(1)
    A + 3 = 3*(B + 3)…….. (2)
    Solve both equations to get A and B

  2. The ratio of the ages of priya and riya is 2:5. After 8 years, their ages will be in the ratio of 2:3. Then the sum of their present ages
    a) 12 years
    b) 14 years
    c) 16 years
    d) 18 years
    e) None of these
    Answer – b) 14 years
    Explanation :
    Let priya age  = 2x and riya age = 5x.
    So, (2x + 8)/(5x + 8) = 2/3, we get x = 2. So sum of priya and riya = 14

  3. The sum of the age of mother and daughter is 100 years. 5 years ago their age were in the ratio of 2:1. The ratio of the age of daughter and mother after 10 years
    a) 2:5
    b) 3:4
    c) 3:5
    d) 4:5
    e) None of these
    Answer – c) 3:5
    Explanation :
    M + D = 100 and  (M – 5)/(D -5) = 2/1
    we get D = 35 and M = 65. So after 10 years ratio = 45/75 = 3/5

  4. The ratio of the ages of two persons are in the ratio of 5:7 and the difference between their ages is 18 years. Find the sum of the ages of the person after 5 years,
    a) 112 years
    b) 115 years
    c) 117 years
    d) 119 years
    e) None of these
    Answer – e) None of these
    Explanation :7x – 5x = 18…data inadequate

  5. If 6 is subtracted from the present age of neha and the remainder is divided by 6, then the present age of mia is obtained. If Mia is 4 years younger to raj whose age is 12 years, then find the age of neha
    a) 50
    b) 52
    c) 54
    d) 58
    e) None of these
    Answer – c) 54
    Explanation :
    (N – 6)/6 = M = 12 – 4 = 8. We will get N = 54

  6. If P age is twice the average age of P, Q and R age’s. Q’s age is one half the average of P, Q and R’s age. If the age of R is 5 years, then find the sum of ages of P, Q and R.
    a) 20
    b) 25
    c) 30
    d) 35
    e) None of these
    Answer – c) 30
    Explanation :
    P = 2*(P + Q+ R)/3
    Q = (1/2)*(P + Q+ R)/3 and R = 5 solve these equations, we will get P = 20, Q = 5 and R = 5

  7. The ratio between the A and B age is 7: 9. If the difference between the present ages of Q and P’s age after 4 years is 2 then what is the total of the present ages of P and Q?
    a) 42
    b) 44
    c) 46
    d) 48
    e) None of these
    Answer – d) 48
    Explanation :
    let age of B is 9x and that of A is 7x. So
    9x – (7x +4) = 2, x = 3
    So sum will be = 27 + 21 = 48

  8. Ritu married 6 years ago. Today her age is 5/4 times her age at the time of her marriage. Her daughter age is 1/5 of her age. What is the ratio of ritu age to her daughter age after 6 years?
    a) 2:1
    b) 3:1
    c) 4:3
    d) 5:2
    e) None of these
    Answer – b) 3:1
    Explanation :
    R = (5/4)*(R – 6)
    R = 30 years and daughter age = 30/5 = 6 years.
    After 6 years ratio will be = 36/12 = 3:1

  9. 6 years ago Ram was twice as old as Shyam. If the ratio of their present ages is 9:5 respectively, what is the difference between their present ages in year?
    a) 20 year
    b) 22 year
    c) 24 year
    d) 26 year
    e) None of these
    Answer – c) 24 year
    Explanation :
    R – 6 = 2*(S – 6)
    put R = 9x and S  = 5x, we will get x = 6
    so difference between ages is 4*6 = 24 years

  10. The sum of the ages of a mother and her son is 45 years. Five years ago, the product of their ages was 3 times the mother age at that time, then the present age of the son,
    a) 8
    b) 10
    c) 12
    d) 14
    e) None of these
    Answer – a) 8
    Explanation :
    M + S = 45
    (M -5)*(S – 5) = 3*(M – 5) so, S = 8 years
