The age of Alex in 2000 was 1/50th of his birth year, What is his age in 2016?
The age of Alex in 2000 be x, (2012-x)/49=x,2012-x=49x,2000=50x, x=40,In 2016 his age will be 40+16=56
The ratio between the present ages of M and N is 6 : 7. If N is 4 years old than M. What will be the ratio of the ages of M and N after 4 years?
Let M's age and N's age be 6x years and 7x years respectively
Then, 7x - 6x = 4 or x = 4
Required ratio = (6x + 4) : (7x + 4) = 28 : 32 = 7 : 8
In a class, there are 30 students. The average age of all students is 19 years. The average increases by 1 when the teacher’s age also included. What is the age of the teacher?
Avg x Number = Total 19 years x 30 nos = 570 years ... (1)
20 years x 31 nos = 620 years ... (2)
Teacher’s age = (2) - (1) = 620 – 570 = 50 Years.
At present, the ratio between the ages of Akhin and Diwakar is 4 : 3. After 6 years, Akhin’s age will be 26 years. What is the age of Diwakar at present?
Let the present ages of Akhin and Diwakar be 4x years and 3x years respectively. Then, 4x + 6 = 26
4x = 20
x = 5
Diwakar's age = 3x = 15 years.
A father is thrice as old as his younger son. 25 years ago, the age of the father was 13 times the age of the son. The present age of the father (in years) is
Let younger son's age = x. Then father's age = 3x
13 (x - 25) = (3x - 25)
10x = 300
x = 30
Father's present age = 90 years.
Ten years ago, Vimal was thrice as old as Jeeva was but 10 years hence, he will be only twice as old. Find Vimal’s present age.
Let Vimal’s present age be x years and Jeeva’s present age be y years.
Then, according to the first condition,
x - 10 = 3(y - 10) or, x - 3y = -20 ..(1)
Now. Vimal's age after 10 years = (x + 10) years
Jeeva's age after 10 years = (y + 10)
(x+10) = 2 (y+10) or, x - 2y = 10 ..(2)
Solving (1) and (2), we get x = 70 and y = 30
Vimal's age = 70 years and Jeeva's age = 30 years.
If Jitin was 1/3rd as old as Nitin 5 years back and Jitin is 17 years old now, How old is Nitin now?
Jitin’s age today is 17 years, Hence, 5 years back, he must be 12 years old. Thus, Nitin must be 36 years (3 x 12) old 5 years back Nitin must be 41 years (36 + 5) old today.
The ages of Anjan, Bhanu and Charan together total 185 years. Bhanu is twice as old as Anjan and Charan is 17 years older than Anjan. Then, the respective ages of Anjan, Bhanu and Charan are
40, 86 and 59 years
42, 84 and 59 years
40, 80 and 65 years
Let Anjan's age be x years
Bhanu's age be 2x years
Charan's age = (x + 17) years
According to the question,
x + 2x + (x + 17) = 185
4x = 185 - 17 = 168 x = 42
Anjan's age = 42 Years
Bhanu's age = 84 Years
Charan's age = 42 + 17 = 59 years.
Present ages of Santosh and Arjun are in the ratio of 5 : 4 respectively. Three years hence, the ratio of their ages will become 11 : 9 respectively, What is Arjun’s present age in years?
Can't be determined
Let the present ages of Santosh and Arjun be 5x years and 4x years respectively
Then, (5x + 3)/(4x + 3) = 11/9
9 (5x + 3) = 11 (4x + 3)
x = 6
Arjun's present age = 4x = 24 years.
A man is 4 times as old as his daughter today. Twenty years later, he would be just twice as old. At the time of birth of his daughter, how much old must the man be?
Let the ages of daughter and man today by 'x' and '4x' years respectively.
4x + 20 = 2 (x + 20) ---> As per information
x = 10 years ==> 4x = 40 years.
At the time of birth of his daughter, man must be 40 - 10 = 30 old
The total of the ages of Jayaram, Praveen and Sarath is 93 years. Ten years ago, the ratio of their ages was 2 : 3 : 4. What is the present age of Sarath?
Let the ages of Jayaram, Praveen and Sarath 10 years ago be 2x, 3x and 4x years respectively
Then, (2x + 10) + (3x + 10) + (4x + 10) = 93
9x = 63
x = 7
Sarath's present age = (4x + 10) = 38 years.
