Question

The sum of ages of 5 children born at the interval of 3 years each is 50 years. What is the age of youngest child ?


Answer

Let the age of 5 child be x,(x+3),(x+6),(x+9),(x+12).
$= > x + (x + 3) + (x + 6) + (x + 9) + (x + 12)$
$= > x + x + 3 + x + 6 + x + 9 + x + 12$
$= > 5x + 30 = 50$
$= > 5x = 50 - 30$
$= > 5x = 20$
$= > x = 4$
Ans) Hence the age of youngest child is 4 years.

Answer 2

Answer:

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
