Meena married 10 years ago. Today her age is 7/5 times her age at the time of her
marriage. Her daughter age is 1/5 of her age. What is the ratio of Meena‘s age to her
daughter age after 5 years?
Correct
Let‘s Meena‘s age be x
X=7/5*(x-10)==>x=35.
And her daughter‘s age 35/5=7.
After5yrs M:D=40:12==>10:3

Father is aged three times more than his son kavin. After 8 years, he would be two and
a half times of kavin‘s age. After further 8 years, how many times would he be of
kavin‘s age?
Correct
Assume that kavin‘s present age =x.
Then, father‘s present age =3x+x=4x
After 8 years, father‘s age=2 ½ times of kavin‘s age.
(4x+8)=2 1/2(x+8)==>3x=24
X=8.
Then x kavin‘s age=8,her father‘s age 4*8=32.
After 8+8 =16yrs.their age‘s are 24 and 48.
It is 2 times.

Mr. X has three sons namely P, Q and R. P is the eldest son of Mr. X while R 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 P after three years?
Correct
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] P‘s present age = 16; after
three years = 19

Three years ago the average age of Ramesh‘s family having 5 members was 17 years.
Ramesh becomes father but the average age of his family is same today. What is the
present age of baby?
Correct
The age of 5 members 3 years ago=17×5=85 years
Total age of 5 members at present= 85 + (5×3)=100 years
Total age of 6 members at present =17×6=102 years…
(as average is same at present so we took 17)
Hence, age of baby = 102-100 = 2 years
Incorrect
The age of 5 members 3 years ago=17×5=85 years
Total age of 5 members at present= 85 + (5×3)=100 years
Total age of 6 members at present =17×6=102 years…
(as average is same at present so we took 17)
Hence, age of baby = 102-100 = 2 years

The ratio between the present ages of A and B is 6:7. If B is 4 years old than A, what
will be the ratio of the ages of A and after 4 years.
Correct
Let A age and B age is 6x years and 7x years.
Then 7x – 6x = 4 <=> x = 4
So required ratio will be (6x+4): (7x+4) => 28:32 => 7:8
Incorrect
Let A age and B age is 6x years and 7x years.

The present ratio of ages of A & B is 11:12 and the ratio of ages of A‘s 2yr back and B‘s
6yr after is 2:3. Find age of A 6yr after?
Correct
A/B = 11/12 ……….(1)
(A-2)/(B+6) = 2/3………(2)
By solving above equation we will get A = 22
So age of A 6yr after = 22+6 =28yr
Incorrect
A/B = 11/12 ……….(1)

5 years ago the ratio of ages of A and B are 5:7 and 10 years hence from now ratio will
become 4:5. Find the average of present age of A and B.
Correct
—————————–A ———— B
5 years ago ————- 5 ———- 7
10 years hence ——– 4 ———–5
Difference = ——– (-1)——– (-2)
to make these two difference equal multiply the second equation with (7-5)=2
So we get
—————————–A ———— B
5 years ago ————- 5 ———- 7
10 years hence ——– 8 ———–10
Difference = ——– (+3)——– (+3)
3=15 years (5 ago + 10 hence)
1=5 years
=> 5 = 25 years (5 years ago of A)
=>7=35 years (5 years ago of B)
Hence A=25+5=30
B=35+5=40 years
Avg=70/2=35
