    Answer (1 of 3): Let us assume his present age to be x. Now, After ten years his age will be x+10 Before five years his age was x-5 Now, x+10=5(x-5) x+10=5x-25 x-5x=-25-10 -4.x=-35 x=35/4 x=8.75 His present age is 8.75 yrs or in other words 8 years 9 months. Hope this helps!!

    What is John’s present age, if after 15 years his age will be 3 times his age 6 years back?

    Let Present age = x

    After 15 years age will be x+15 which is equal to 3*(x-6)

    i.e. x+15=3x-18 15+18=3x-x=2x

    33=2x; x=16.5 So Mr John’s present age is 16years & 6 months

    What is John’s present age, if 10 years later his age will be 5 times his age 6 years ago?

    Let the present age of John be x years.

    ATP, (x+10) = 5(x-6) => x + 10 = 5x - 30 => 40 = 4x => x = 10

    Thus, the present age of John is 10 years.

    Hope this answers your question. Good day to you.

    After 36 years, Rehan will be 5 times as old as he is now. What is his present age?

    Let’s call the current age X, so, in 36 years it will be 5 times as it is now, which means:

    x + 36 = 5x

    If you put -x on both sides of the equation:

    x + 36 - x = 5x - x 36 = 4x

    And now dividing by 4 on both sides:

    36/4 = 4x/4 Which means: 9 = x

    So the answer is “Rehan’s current age is 9 years old”

    Hope it helped :)

    A man’s present age is eight times his son’s age. After two years, his age will be six times his son’s age. What are their present ages?

    Man’s present age=8x

    Son’s present age=x After 2 years…

    Man’s age after 2 years: 8x+2

    Here the question tells us that 6 times the son’s age is the father’s age.

    So…

    6(x+2) is the son’s age in 2 years.

    How to Solve Problems on Ages?

    As aptitude questions on ages are frequently asked in almost every competitive exam, be it the GMAT, GRE, SAT, CAT, etc., applicants should definitely know how to solve these within minimum time.

    To make this easier for you, let’s take a look at some of the basic mathematical concepts and tricks related to problems on ages:

    If the present age of a person be X, then

    Age after n years = X + n

    Age n years ago = X – n

    n times the present age = nX

    If ages in the numerical are mentioned in the ratio A:B, then A:B will be AX and BX

    If the sum of ages is X and Y and the ratio of their ages is p:q respectively, then you can determine the age of Y by using the formula shown below:

    Age of Y = Ratio of Y/ Sum of ratios x sum of ages

    Age of Y = q/ (p+q) x A

    Points to Remember

    After reading the problems on ages, assume the unknown age to be some variable, let say ‘X’.

    Convert the statements in the question into mathematical equations.

    Calculate the variable by solving the equations and the obtained value must satisfy the conditions given in the problem.

    Sample Problems on Ages

    Questions on ages in a competitive exam are classified into four categories. Below are some examples to understand the concept explained above:

    Type 1 – Calculate the Present Age

    What is John’s present age, if 10 years later his age will be 5 times his age 6 years ago? 

    16.2 years 7.7 years 8.7 years 10 years

    Correct option is 4

    Let John’s present age be X

    John’s age 6 years ago = (X-6)

    John’s age 10 years later = (X+10)

    We are given that John’s age after 10 years (x + 10) is 5 times his age 5 years ago (x-6).

    Therefore, (x +10) = 5 (x-6)

    Solving the equation, we get

    x + 10 = 5(x-6) x+10 = 5x – 30 4x = 40 x= 10

    Type 2 – Determine the Ages in Ratio Form

    One year ago, the ratio of Parul and Atima’s age was 5:6 respectively, after 4 years, the ratio becomes 6:7. Find the present age of Atima.

    25 years 26 years 31 years 35 years

    Correct option is 3Hint: If ages in the numerical are mentioned in ratio A: B, then we assume ages as Ax and Bx

    We are given the age ratio of Parul and Atima = 5:6

    One year ago, their age was 5x and 6x. Hence at present, Parul’s age = 5x+1 and Atima’s age = 6x+1

    After 4 years, Parul’s age = (5x+1) + 4 = (5x + 5)

    Atima’s age =  (6x+1) + 4 = (6x + 5)

    After 4 years, this ratio becomes 6:7

    Therefore,

    Parul’s age/6 = Atima’s age/7

    (5x + 5) /  (6x + 5) = 6/7

    7 (5x + 5) = 6 (6x + 5)

    35x + 35 = 36x + 30 36x – 35x = 35 – 30 X = 5

    Parul’s present age = (6x+1) = (6×5+1) = 31 years

    Atima’s present age = (5x+1) = 5×5+1) = 26 years

    Type 3 – Determine a Person’s Age Before x Years

    Shivani is 60 years old and Ritu is 80 years old. How many years ago their age ratio was 4:6?

    10 years 15 years 20 years 25 years

    Correct option is 3

    Let us assume x years ago

    At present Shivani is 60 years old and Ritu is 80 years old.

    X years ago : Shivani’s age = (60-x) and Ritu’s age (80-x)

    Ratio of their ages x years ago was 4:6

    (60-x) / (80-x) = 4/6

    6 (60-x) = 4 (80-x) 360-6x = 320-4x 6x – 4x = 360 – 320 2x = 40 x = 20

    Therefore, 20 years ago their age ratio was 4:6
