Answer 1

➣ Correct Question

Miraj mother is four times as old as Miraj after 5 years her mother will be three times as old as Miraj. Find their present ages.

➣ Answer

• Present age of Miraj = 10 years.

• Present age of Miraj's mother = 40 years.

➣ Given

• Miraj mother is four times as old as Miraj after 5 years her mother will be three times as old as Miraj.

➣ To Find

• The present age of Miraj and his mother.

➣ Step By Step Explanation

Given that Miraj mother is four times as old as Miraj after 5 years her mother will be three times as old as Miraj.

We need to calculate their present ages.

➵ Assumption

Let Miraj age be x then his mother's age will be 4x.

After 5 years age of Miraj will be x + 5 and his mother's age will be 4x + 5 and will be three times as old as Miraj.

So let's do it !!

➵ Equation

$\dag\underline{\boxed{ \tt{ \color{purple}{4x + 5 = 3(x + 5)}}}}$

➵ Solution of Equation

$\longmapsto\tt4x + 5 = 3(x + 5) \\ \\\longmapsto \tt 4x + 5 = 3x + 15 \\ \\\longmapsto \tt 4x - 3x = 15 - 5 \\ \\\longmapsto \bf\red{ x = 10}$

Therefore, present age of Miraj = x => 10 and present of his mother = 4x => 40 years.
