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 ratio of the present ages of Sunita and Vinita is 4:5. Six years hence the ratio of their ages will be 14:17. What will be the ratio of their ages 12 years hence?
Answer : A
Explanation
Suppose the present ages of Sunita and Vinita be 4x years and 5x years respectively. Six years hence (4x + 6)/(5x + 6) = 14/17 Or, 68x + 102 = 70x + 84 Or, 2x = 18 Or, X = 9 Ratio of ages of Sunita and Vinita after 12 years = (4x + 12) : (5x + 12) = (36+12) : (45+12) = 48:57 = 16:19
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 - Prabhakar is 15 years older than Navin and Navin is 25 years younger than Ashok. Which of the following represents the difference between the ages of Ashok and Prabhakar?

According to question, P = N + 15 A = N + 25 A - P = (N + 25) - (N + 15) = 10 years
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 - 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 - If 4:1 is the ratio between mother and daughter and the sum of their age is 196. What should be the age ratio between mother and daughter after the period of 5 year?
Answer : C
Explanation
Let mother age be4 x year and her daughter age is x year. 4x*x = 196 ⇒ x2 = 49 ⇒ x = 7 Present age of mother is 7*4 = 28 year and son present age = 7 years. Required ratio = (28+5) : (7+5) = 33 : 12 = 11 : 4
Q 8 - Before 6 year Radha got married . if we compare the marriage time with the present time , present time would be 5/4 times from the marriage time. At the present time son got 1/10 times in the comparison of his mother age . find out the present time age of his mother?
