1. 10
2. 9
3. 8
4. 7
Answer & Explanation Answer:- 1 Explanation :- Let the age of C = x years 2. A man’s age is 125% of what it was 10 years ago, but 8313% of what it will be after 10 years. What is his present age? Answer & Explanation Answer:- 3 Explanation :- Lets assume the age before 10 years = x , Therefore 3. A man is 24 years older than his son. In two years, his age will be twice the age of his son. What is the present age of his son? Answer & Explanation Answer:- 2 Explanation :- Let’s suppose son’s present age = x years. 4. Present ages of Kiran and Syam are in the ratio of 5 : 4 respectively. Three years hence, the ratio of their ages will become 11 : 9 respectively. What is Syam’s present age in years? Answer & Explanation Answer:- 4 Explanation :- Kiran’s age : Syam’s age = 5x : 4x 5. The sum of ages of 5 children born at the intervals of 3 years each is 50 years. Find out the age of the youngest child? Answer & Explanation Answer:- 3 Explanation :- Let the age of younger child = x years
Therefore, B’s age = 2x years & A’s age = (2x + 2) years
x + 2x + (2x + 2) = 27
5x + 2 = 27
x = 5
So , B’s age = 2x = 2 * 5 = 10 years
1. 70
2. 60
3. 50
4. 40
(125x/100) = x + 10
125x = 100x + 1000
25x = 1000
x = 40
His present age = x + 10 = 40 + 10 = 50 years
1. 23 years
2. 22 years
3. 21 years
4. 20 years
Therefore, man’s present age = (x + 24) years
(x + 24) + 2 = 2(x + 2)
x + 26 = 2x + 4
x = 22
1. 28
2. 27
3. 26
4. 24
Let’s suppose the present age of Kiran = 5 x
Present age of Syam = 4x
After 3 Years, Ratio Become 11 : 9
That means (5x + 3) / (4x + 3) = 11/9
9(5x + 3) = 11(4x + 3)
45x + 27 = 44x + 33
x = 6 years
Syam’s Present age = 4x = 4 * 6 = 24 years
1. 6 years
2. 5 years
3. 4 years
4. 3 years
As there is a gap of 3 years in ages of all the 5 childrens
Therefore According to question
x + (x + 3) + (x + 3) + (x + 3) + (x + 3) = 50
5x = 20
x = 4
Age of younger child = 4 years
