Six years ago, father’s age was five times the age of the son. After 6 years, what will be son’s age? Answer & Explanation Answer:- 4 Explanation :- Lets assume the present age of son = x years 4. Kiran is younger than Bineesh by 7 years and their ages are in the respective ratio of 7 : 9, how old is Kiran? Answer & Explanation Answer:- 2 Explanation :- Kiran’s Age : Bineesh’s age = 7 : 9 5. Six years ago, the ratio of the ages of Vimal and Saroj was 6 : 5. Four years hence, the ratio of their ages will be 11 : 10. What is Saroj’s age at present? Answer & Explanation Answer:- 3 Explanation :- Vimal’s Age 6 years ago = 6x
Therefore, (38 – x) = x
2x = 38 => x = 19
Son’s age five years ago = 19 – 5 = 14 years
1. 10 years
2. 12 years
3. 8 years
4. 5 years
Ayisha’s father’s age after 10 years = 2(10 + 10) = 40
Ayisha’s father’s present age = 40 -10 = 30
Ayisha’s present age = 30 / 6 = 5 years
1. 23 years
2. 22 years
3. 21 years
4. 20 years
Therefore , Present age of father = (60 – x)
(60 – x) – 6 = 5(x – 6)
54 – x = 5x – 30
x = 14
After 6 years , Son’s age = 14 + 6 = 20
1. 25
2. 24.5
3. 24
4. 23.5
Let Kiran’s Age = 7x & Bineesh’s age = 9x
9x – 7x = 7
x = 3.5
Kiran’s age = 7x = 7 * 3.5 = 24.5 years
1. 18
2. 17
3. 16
4. 15
Saroj’s Age 6 years ago = 5x
Their Present Ages are (6x + 6) & (5x + 6)
After 4 years
(6x + 6 + 4) / (5x + 6 + 4) = 11/10
(6x + 10) / (5x + 10) = 11/10
10(6x + 10) = 11 (5x + 10)
x = 2
Saroj’s Present Age = 5x + 6 = (5 * 2) + 6 = 16
