Correct Question:

Miraj Mother is four times as old as Miraj. After five years, her mother will be three times as old as she will be then,Find their present ages.

━━━━━━━━━━━━━━━━━━━━━━━━

Given:

☆Miraj's Mother is four times as old as Miraj.

☆After five years, her mother will be three times older than Miraj

━━━━━━━━━━━━━━━━━━━━━━━━

Solution:

Let's

Present age of Miraj be = x years

As Miraj's Mother four time old as Miraj

So,

Miraj's mother's age must be = 4x years.

After five years,

Miraj's age will be = (x + 5) years

Mothers age will be = (4x + 5) years

⠀

\mathfrak{ \text{A}ccording\; to\:the\;given\; Condition}AccordingtothegivenCondition

\begin{gathered} \bf (4x + 5) = 3(x + 5) \\ \\ \sf4x + 5 = 3x + 15 \\ \\ \sf 4x - 3x = 15 - 5 \\ \\ \sf \red{ \boxed{ \boxed{ \bf x = 10 }}}\end{gathered}

(4x+5)=3(x+5)

4x+5=3x+15

4x−3x=15−5

x=10

So,

Miraj's Present age = x = 10 years.

Miraj's mother's Present age = 4(x) = 4(10) = 40 years.
