- The present age of Sriram is twice that of his brother. Five years hence the ratio of their ages will be 21:13. What is the present age of his brother ?
7 years8 years6 years9 years5 yearsOption B

2x+5/x+5 = 21/13

26x+65 = 21x+105

5x=40

x = 8 years - The sum of the age of Father and his daughter is 62 years. After 5 years, the age of father will be five times that of the son. What is the age of the Son ?
3 years9 years4 years7 years5 yearsOption D

Son = 62-5(5-1)/5+1 = 62-20/6 = 42/6 = 7 years - One year back, Ria was six times as old as her daughter. Six years hence, Riaâ€™s age will exceed her daughterâ€™s age by 15 years. The ratio of the present ages of Ria and her daughter is?
13 : 510 : 717 : 1310 : 1719 : 4Option E

Ages of Ria and her daughter = 6x, x

[6x + 1 + 6] â€“ [x + 1 + 6] = 15

5x = 15; x = 3

Ratio = 6x + 1 : x + 1 = 19 : 4 - Suresh age is 125% of what it was ten years ago, but 250/3% of what it will be after ten years. What is the present age of Suresh?
10 years20 years50 years30 years40 yearsOption C

Sureshâ€™s age before 10 years = x

125x/100 = x + 10

125x = 100x + 1000

=> x = 40

Present age = x + 10 = 50 years - Sanjayâ€™ father was 30 years old when he was born. His motherâ€™s age was 24 when his sister who is 5 years younger to him, was born. What is the difference between the age of Sanjay father and mother?
14 years11 years13 years10 years12 yearsOption B

Sanjayâ€™age = F â€“ 30

Sisterâ€™s age = F â€“ 35

M = 24 + Sisterâ€™s age

M = 24 + F â€“ 35

F â€“ M = 11 years - Amar got married 6 years ago. His present age is 5/4 times his age at the time of his marriage. Amarâ€™s brother was 5 years younger to him at the time of his marriage. What is the present age of Amarâ€™s brother?
24 years25 years21 years22 years20 yearsOption B

Present age of Amar = x

Present age of Amarâ€™s sister = y

x = (x-6)(5/4)

x = 30

Present age of Amarâ€™s brother = 30 â€“ 5 = 25 years - The respective ratio between the present age of Manu and Mina is 5:x. Manu is 9 years younger than Pooja. Poojaâ€™s age after 9 years will be 33 years. The difference between Minaâ€™s and Manuâ€™s age is same as the present age of Pooja. What is the value of x?
13 years11 years12 years10 years14 yearsOption A

Pooojaâ€™s age after 9 years = 33 years

Poojaâ€™s present age = 33 â€“ 9 = 24 years

Manuâ€™s present age = 24 â€“ 9 = 15 years

Minaâ€™s present age = 15 + 24 = 39 years

Ratio between Manu and Mina = 15 : 39 = 5 : 13

x = 13 years - Average age of a group of 32 students is 26 years. If a teacher is included then the average age rises by 1 year,what is the present age of teacher?
38 years40 years44 years59 years50 yearsOption D

Students total age = 32*26 = 832

Students & Teacher total age = 33*27 = 891

Teacher = 891-832 = 59 years - The ages of A and B are in the ratio of 8 : 5 respectively. After 5 years the ratio of their ages will be 7:5. What is the difference in years between their ages.
7 years3 years6 years2 years4 yearsOption C

A:B

= 8:5

=> 16:10

After 5 years

21:15 = 7:5

16-10 = 6 years - Karanâ€™s present age is one fourth of his fatherâ€™s age two years ago. Karanâ€™s fatherâ€™s age will be twice Ramâ€™s age after 10 years. If Ramâ€™s 12th birthday was celebrated 2 years ago, then what is Karanâ€™s present age ?
6 years7 years9 years8 years5 yearsOption C

Ram = 12+2 = 14

Karanâ€™s father = X+10 =2(10+14)

X = 48-10 = 38

John = 36/4 = 9 years
