Question

3)The present age of sumit's mother is four times the
present age of sumit. After 5 years, the sum of their ages
will be 60 years Find their present ages.​

Answer 1

Let present age of Sumit be = x

Age of Sumit's mother = 4x

After 5 years

Sumit = x + 5

Mother = 4x + 5

Sum of ages = 60

=> x + 5 + 4x + 5 = 60

=> 5x = 50

=> x = 10 years

Mother = 40 years

Answer 2

★ Question.

The present age of sumit's mother is four times thepresent age of sumit. After 5 years, the sum of their ageswill be 60 years Find their present ages.

Answer ★

Let the present age of sumit be = x

And,

Age of sumit mother be = 4time of x 4x

Sum of both ages = 60years

Now,

→ According to question

$\implies\tt x+4x=6 \\\implies\tt 5x=60\\\implies\tt x=\frac{60}{5}\\\implies\tt x= 10$

→ Putting x = 10 in both of the ages

→ sumit age = x= 10years

→ Sumit's mother age = 4x = 4×10 = 40years.
