Q 1 - The average age of five officers in a department is 32 years. If the age of their supervisor is added the average increases by 1. What is the supervisor's age?
Answer : C
Explanation
Supervisor?s age = 32 + 6 = 38 years
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 - 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 - What should be the present age of a man if the given condition is such as 15 year hence , a men will be 4 times as old as he was before the period of 15 year?
Answer : D
Explanation
Let man present age be x years. His age 15 year ago = (x-15) years. His age 15year hence = (x+15) years. (x+15) = 4(x-15) ⇒ 3x= 45 ⇒ x = 45
Q 6 - If 6 year is the difference of age of two boys ram and shyam at the present time. After the period of 4 year, the ratio of their age would be 3:4 . find out the shyam age at the present time?
Answer : C
Explanation
Let x year is the ram present age then shyam present age will be (x+6) X+4/ (x+6+4) = 3/4 = x+4/ x+10 = 3/4 ⇒ 4(x+4) = 3(x+10) ⇒ x = 14. Hence , it proves that the present age of shyam = (14+6) = 20 year
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 - 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?
Answer : B
Explanation
Given A-Y = Y-P ⇒ A+P = 2Y Also A+P = 48 Year . so, 2j = 48 ⇒ y = 24 Hence, yusuf is 24 year old.
Q 9 - What should be the present age of A,B and C who have the present age in the proportion of 10 :11:12. 150 was the sum of the ages of all before the period of 5 years.
Answer : D
Explanation
If the present age of A,B and C be 10 x, 11x and 12x years. Sum of their ages now = (150+ 5*3) =165 years. ∴ 10x+11x+12x = 165 ⇒ 33 x = 165 ⇒ x = 5 So, their ages are 50, 55 and 60 years.
Q 10 - 15 year hence, a man will be just 4 times as old as he was 15 years ago . His present age is
Answer : A
Explanation
Let the present age of the men be x years. then (x+15) = 4(x-15) ⇒ 3x= 75 ⇒ x =25 Hence, the present age of the man is 25 years.
