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 - 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 8 :15 is the ratio of sunil and tarun ages than the ratio and tarun change after the period of 9 year and become 11:18 . Find out the age difference between sunil and tarun ?
Answer : B
Explanation
Let sunil age = 8 year and tarun age is = 15 x years. 8x+9 / 15x+9 =11/18 ⇒ 18 (8x+9) = 11(15x+9) ⇒ 144x +162 = 165x +99 ⇒21x = 63 ⇒ x =3 Difference between the ages = (15x-8x)= 45-24 = 21 years
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 - 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 - 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.
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?
Answer : B
Explanation
Let radha age 6 year ago be x year. Then, radha present age = (x+6) years. ∴ x+ 6 = 5x/4 ⇒ 4(x+6) =5x = x =24 Present age of radha = (24+6) = 30 years. Son ?s present age = (1/10* 30) years = 3 years.
Q 9 - Before the period of 16 year, my grandfather was 8 times older in the comparison of me. He would be 3 times of my age 8 years now. Find out the ratio of my grandfather and my age before the period of 8 year.
Answer : D
Explanation
Let my age 16 yrs ago be x years. My grandfather age at that time = 8x years My present age = (x+16) yrs. My grandfather present age = (8x+16) years. 3(x+16+8)= (8x+16+8) ⇒ 3x+72 = 8x+24 ⇒ 5x = 48 ⇒ x = 48/5 Ratio of our ages 8 yrs ago = (x+16-8) /(8x+16-8) = x+8/ 8x+8 (48/5+8)/ (8* 48/5 +5) = 88/424 = 11 :53.
Q 10 - Ajit age after 15 years will be 5 times his age 5 years back . what is the present age of ajit ?
Answer : B
Explanation
Let the present age of ajit be x years. (x+15) = 5(x-5) ⇒ x+15 = 5x-25 ⇒ 4x= 40 =. X = 10
