Q 1 - The ages of Arzoo and Arnav are in the ratio of 11:13 respectively. After 7 years the ratio of their ages will be 20:23. What is the difference in years between their ages?
Answer : C
Explanation
Let the present ages of Arzoo and Arnav be 11x and 13x respectively. According to the question, (11x + 7) / (13x + 7) = 20/23 Or, 26x + 140 = 253x + 161 Or, 260x - 253x = 161 - 140 Or, 7x = 21 Or, x = 3 Difference between their ages = 13x - 11x = 2x = 2*3 = 6 years
Q 2 - In a family the average age of the father and mother is 38 years whereas the average age of father, mother and their only daughter is 28 years. Then the age of the daughter is -
Answer : D
Explanation
The age of the daughter = (3*28) - (2*38) = 84 - 76 = 8 years
Q 3 - Six years back Seema was half of that of Rupa in age. Four years hence the respective ratio of their ages would be 3:5. How old is Rupa at present?
Answer : D
Explanation
Let the present ages of Seema and Rupa be x years and y years respectively. According to question, (y - 6) = 2(x - 6) Or, y - 6 = 2x - 12 Or, 2x - y = 6 ...(i) Similarly, (x + 4)/(y + 4) = 3/5 Or, 5x + 20 = 3y + 12 Or, 5x - 3y = - 8 ... (ii) From equ (i) and equ (ii), 6x - 3y = 18 5x - 3y = -8 We get, x = 26 years and y = 46 years
Q 4 - If 3:4 is the present age ratio of anil and varun but 5 year later , the ratio of their age change and become 4:5 . Find out the present age of varun ?
Answer : C
Explanation
If anil age is 3x year and 4x is the varun age. 3x+5/ 4x+5 =4/5 ⇒5(3x+5) = 4(x+5) ⇒ 15x+25 = 16x+20 ⇒ x= 5 Varun age = (4*5) =20 year
Q 5 - If 100 year is equal to the sum of the ages of father and son. 2:1 was the ratio of father and son before the period of 5 years . Find out the ratio of ages which would be after the period 10 year.
Answer : B
Explanation
If x is the father age ,then son age will be (100-x) x-5/ (100-x)-5 =2/1 ⇒ (x-5)= 2(95-x) ⇒ x =-5= 190 -2x ⇒ 3x =195 ⇒ x =65 father age = 65 yrs. And son age = 100-65 = 35 year required ratio = (65+10) / (35+10) =75/45 = 5:3
Q 6 - Suraj was thrice as old as karan 6 year before. Suraj will be 5/3 times as old as karan 6 year hence. What should be the age of karan at the present time?
Answer : A
Explanation
Before 6 year if suraj age is x year then karan age will be 3x year. Suraj age at the present time = (x+6) and karan age (3x+6) yrs. Suraj age after 6 year = (x+12) year Karan age after 6 year = (3x+12) year (3x+12) =5/3(x+12) ⇒ 9x+36 = 5x+60 = 4x = 24 ⇒ x =6 Karan age at the present time = 6+6 = 12 years.
Q 7 - At the present time a man age is 3 times in the comparison of his son . the man would be double than his son after 15 year . In that case what should be the age of his son at the present time?
Answer : A
Explanation
Let the son age be x years and . man age now be 3x years. 3x+15 = 2(x+15) ⇒ x =15 Present age of the son = 15 years.

Answer : C
Explanation
Let vijay age 5 years ago be x years. Then, vipin age 5 years ago = 3x years. x+5 = 17 ⇒ x = 12 present age of vipin = (3*12+5) = 41 yrs.
Q 9 - Nitesh and raju is 40 and 60 years old. Find out the time howmuch year ago, the ratio of their age 3:5 ?
Answer : B
Explanation
Let the required ratio be x years ago , then 40-x/ 60-x = 3/5 ⇒ 5(40-x) = 3(60-x) =. 2x = 20 ⇒ x = 10
Q 10 - 15 year hence, a man will be just 4 times as old as he was 15 years ago . His present age is
