ExplanationLet x = the youngest child. Each of the other four children will then be x+3, x+6, x+9, x+12.
We know that the sum of their ages is 50 .
so, x+(x+3)+(x+6)+(x+9)+(x+12) = 50
=> x= 4
The youngest child is 4 years old.

Correct Answer: 40
Explanation:
Let daughter?s age = A and mother?s age = B
Given: 2A+B = 70 and A+2B = 95
Solving B, we will get B = 40.
Correct Answer: data inadequate
Explanation:
Let Meena?s age = A.
Then Sivagami?s age = A + 2
After 6 years the total of their ages will be 7 times of what?
Not clear.
So the given data are inadequate.
Correct Answer: 60 yrs
Explanation:
Let the Father be x years when he died
Average Age 10 years ago be A
Total Age 10 years ago = 6*A
Total Age after 10 years(Just before father's Death) = 6A + 6*10 = 6A + 60
Father Died and Baby was born => the Total number of people in the family is Same (6)
Baby born today so age of baby = 0
(6A +60 - x)/6 = 6A/6
=> A + 10 -(x/6) = A
=> x/6 = 10
=> x = 60
Therefore we can conclude that the father was 60 years old when he died.
Correct Answer: 70 years
Explanation:
Take A's age as a, B's age as b. a + b = 60 a = 2b So, b + 2b = 60 3b = 60 b = 20 a = 40 So A is 40, B is 20. In 5 years' time, A will be 45, B will be 25. so the sum of their ages will be 70
Correct Answer: 24.5
Correct Answer: 22
Explanation:
Let the son's present age be x years. Then, man's present age = (x + 24) years
=> (x + 24) + 2 = 2(x + 2)
=> x + 26 = 2x + 4
So, x = 22
Correct Answer: 15
Explanation:
Krish?s age = 3A and Vaibhav?s age = 5A
(3A+9)/(5A+9) = 3/4
=> 4 (3A + 9) = 3 (5A + 9)
=> A = 3
Therefore, Vaibhav?s age = 15 years.
Correct Answer: 6:5
Explanation:
Let, Maala?s age = 4A and Kala?s age = 3A
Then 4A + 3A = 28
A = 4
Maala?s age = 16 years
and Kala?s age = 12 years
Proportion of their ages after 8 is = (16 + 8) : (12 + 8)
= 24 : 20
= 6 : 5
Correct Answer: 41
Explanation:
Raj?s age today = 17 decades,
Hence, 5 decades back, he must be 12 years old.
Rahim must be 36 years old, Because (3×12).
5 years back Rahim must be 41 years old today. Because (36+5).
Correct Answer: 35
Explanation:
Let A's age 10 years ago = x years.
Then, B's age 10 years ago = 2x years.
(x + 10) / (2x+ l0) = 3/4
=> x = 5.
So, the total of their present ages =(x + 10 + 2x + 10)
= (3x + 20) = 35 years.
