Question

The sum of ages of 55 children born at interval of 33 yrs is 5050yrs .what is the age of youngest child.

Answer 1

Step-by-step explanation:

Since, the children were born at the interval of three years ,let us assume their age as x, x+3,x+6,x+9,x+12.

given- the sum of five children is 50

therefore,

x+x+3+x+6+x+9+x+12 = 50

5x+30 = 50

5x = 50-30

5x=20

x=4

Hence, age of the youngest child is 4 years.

Answer 2

Answer:

4

Step-by-step explanation:

suppose the age of youngest child is X(child 1)

then the age of next to younger is x+3(child 2)

next x+3+3(child 3)

next x+3+3+3(child 4)

x+3+3+3+3 (child 5)

so

x+x+3+x+3+3+x+3+3+3+x+3+3+3+3=50

or 5x+30=50

or 5x=50-30=20

or x=29/5 =4
