Q 2 - The resent ages of A, B and C are in the ratio of 8:14:22 respectively. The resent ages of B, C and D are in the ratio of 21:33:44 respectively. Which of the following represents the ratio of the present ages of A, B, C and D respectively.
Answer : A
Explanation
A : B : C = 8 : 14 : 22 = 12 : 21 : 33 B : C : D = 21 : 33 : 44 Therefore, A : B : C : D = 12 : 21 : 33 : 44
Q 3 - The ratio of the present ages of a son and his father is 1:5 and that of his mother and father is 4: 5. After 2 years the ratio of the ages of the son to that of his mother becomes 3 : 10. What is the present age of the father?
Answer : D
Explanation
Let the present age of the son be x years. present age of the father = 5x years and that of the mother = 4x years. 2 years hence, age of son = (x + 2) years And age of the will be = (4x + 2) years As per the question, (x + 2)/(4x + 2) = 3/10 Or, 10 (x+2) = 3 (4x + 2) Or, 10x + 20 = 12x + 6 Or, 2x = 14 Or, x = 7 Present age of father = 5x = 5*7 = 35 years
Q 4 - A man five times older in the comparison of his son in the present time but before the period of 5 year the father age in the comparison of his son was 10 times older . Find out present age of the father?
Answer : A
Explanation
Let the present age of the son be x year. Then , present age of the man = 5x year ∴ (5x-5 = 10 (x-5) ⇒ 5x= 45 ⇒ x = 9 Age at the present time of the father is = (5*9) = 45 year
Q 5 - If 3:11 is the ratio of ram and his mother but 24 year is the age difference between ram and his mother . What should be the age ratio of ram and his mother after 3 years ?
Answer : A
Explanation
If present age of ram is 3x year then his mother age will be = 11x years. Then ,(11x-3x) = 24 ⇒ 8x = 24 ⇒ x = 3 3 year after their age ratio will be = 3x+3/ 11x+3 = (3*3+3)/(11*3+3) =12/36 = 1/3 =1: 3
Q 6 - 18 year was the average age of A and B before the period of 3 year . if we add C in them , in that case the average become change and the new average is 22. What should be the present age of C?
Answer : A

Sum of the ages of A and B , 3 years ago = (18*2) years =36 years Sum of the present age of A and B = (36+3*2) year = 42 years Sum of the present age of A, B and C = (22*3) = 66 years Present age of C = 66- 42 = 24 years
Q 7 - A mother have 7 times in the comparison of her daughter at the time of 1 year ago . At the present time mother age is equal to the square of her son . What should be the time age of mother?
Answer : B
Explanation
Let the present age of the son be x years. Man present age =7(x-1)+1 years = (7x-6 ) yrs. 7x-6 = x2 ⇒ x2-7x+6 = 0 ⇒ (x-6)(x-1) =0 ⇒ x =6 or x =1 ∴ present age of men = (7*6-6) = 36 yrs.
Q 8 - A mother was 4 times older in the comparison of her daughter before the period of 10 year. The mother age would be double in the comparison of her daughter after 10 year. What should be the present age of the daughter ?
Answer : C

Let daughter age 10 year ago be x years. Mother age 10 years ago = 4x years 2(x+20) = (4x+20) ⇒ 2x = 20 ⇒ x =10 Present age of daughter = (x+10) = 20 years.
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
