The sum of ages of 5 children born at the intervals of 3 years each is 50 years. What is the age of the youngest child?
Answer: Option
Explanation:
Let the ages of children be x, (x + 3), (x + 6), (x + 9) and (x + 12) years.
Then, x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50
5x = 20
x = 4.
Age of the youngest child = x = 4 years.

@Sonam.
let youngest son Tashi age be x and father's age be y age of Dema be a, And the age of Sangay be b.
y=x+30.
a=x+2.
b=a+3.
a+b+x=52.
x+2+a+3+x=52.
x+2+x+2+3+x=52.
3x+7=52.
3x=45.
x=15.
y=15+30.
y=45.
The age of the father is 45.

If I take 1+4+7+10+13 = 35.
35x = 50.
Then the youngest child is 50/35, is it a wrong method?

The answer is 4, because if you get 4+7+10+13-16 =50. Following their 3 years interval. Therefore, 4 is correct.

@Sudheer.
It is right. x= 16. So, younger ones age will be (x-12), which is 4.
Hence the answer.

x+(x+3)+(x+6)+(x+9)+(x+12)=50.
5x+30=50,
5x=50-30,
5x=20,
x=20/5,
x=4.
Ans=4.
5x+30=50,
5x=50-30,
5x=20,
x=20/5,
x=4.
Ans=4.

Divide the sum of the ages by total no of children 50/5=10.
Now as we know that the age varies by 3 years...so take 10+3 &10-3=13&7.
then again take the age and sub and add 3. i.e; 13+3&7-3=16&4,
Now add all the operations 4 + 7 + 10 + 13 + 16 = 50.
