Q 1 - The average age of a man and his son is 48 years. The ratio of their ages is 11:5 respectively. What will be ratio of their ages after 6 years
Answer : D
Explanation
Let the present ages of the man his son be 11x and 5x respectively. According to the question, 11x + 5x = 2*48 Or, 16x = 96 Or, x = 6 Therefore, present age of the man = (11*6) = 66 years Present age of the son = (5*6) = 30 years Hence required ration after 6 years = (66+6) : (30+6) = 72 : 36 = 2:1
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 - One year ago the ratio of Yamini?s and Gamini?s ages was 6 : 7 respectively. Four years hence this ratio would become 7 : 8. How old is Gamini?
Answer : D
Explanation
Let one year ago the ages of Yamini and Gamini be 6x and 7x years respectively. Therefore, present ages will be 6x + 1 and 7x + 1 years respectively. Now four years hence, (6x + 1 + 4) / (7x + 1 + 4) = 7/8 Or, (6x + 5) / (7x + 5) = 7/8 Or, 49x + 35 = 48x + 40 Or, X = 40 - 35 = 5 Hence Gamini's present age = 7x + 1 = 7*5 + 1 = 36 years
Q 4 - The total age of A and B is 12 years more than the total age of B and C. C is how many years younger than A?
Answer : C
Explanation
According to question, A + B = B + C + 12 A = C + 12 C = A - 12 Hence, C is 12 years younger to A.
Q 5 - If 1:2 is the present age ratio of two girls. But 1:3 age ratio of girls was 5 year ago . In that case find out the ratio of age after the period of 5 year?
Answer : C
Explanation
If the present age of two girls is x and 2x years. Then, x-5/ 2x-5 = 1/3 ⇒ 3(x-5) =(2x-5) ⇒ x =10 5 year after their age ratio will be = x+5/ 2x+5 = 10+5/20+5 = 15/25 = 3/5= 3:5
Q 6 - What should be the present age of two person if 5:7 is the present age ratio of two person and 3:5 was the age ratio before the period of 16 year?
Answer : C
Explanation
If the present age of two persons are 5x years and 7x years. 5x-16/ 7x-16 =3/5 ⇒ 5(5x-16) =3(7x-16) ⇒ 4x= (80-48) = 32 ⇒ x =8 Hence, their present ages are 40 years and 56 years.
Q 7 - If Ram and Sham have 36 year and 16 year age . After how much time ram age would be double as old as sham ?
Answer : D
Explanation
Let it be in x years. Then, 36+x = 2(16+x) ⇒ x =4
Q 8 - Yusuf is as much younger to ajay as he is older to pawan , if 48 year is the sum of ajay and pawan then what should be the present age of yusuf?

Let the youngest girl age be x years. Then, X+(x+3) +( x+6) +(x+9) +(x+12) = 50 ⇒5x+30 = 50 ⇒ 5x= 20 ⇒ x =4 Required age = 4 yrs.
Q 10 - 15 year hence, a man will be just 4 times as old as he was 15 years ago . His present age is
