Answer 1

Answer:

Deepak's age is 15 and his mother's age is 45

Step-by-step explanation:

= 1/3 - ? = 1/5

= 1/3 - 1/5 = ?

= 5/15 - 3/15 = ?

= 5/15 - 3/15 = 2/15

So, 2/15 is considered as 6

Then, 1/15 = 3

5/15 = 3 * 5 = 15 is Deepak's age

15 * 3 = 45 is his mother's age

Answer 2

Answer:

$\huge{\boxed{\underline{\tt \red{\dag Let's \: do \dag}}}}$

Let's take age of deepak now = x

so, his mother's age = 3x

6 years ago ,

Deepak's age =x - 6

Mother's age = 3x -n6

$\begin{gathered}5(x - 6) = 3x - 6 \\ 5x - 30 = 3x -6 \\ 5x = 3x - 6 + 30 \\ 5x = 3x + 24 \\ 5x - 3x = 24 \\ 2x = 24 \\ x = \frac{24}{2} = 12\end{gathered}$

Age of deepak now = 12

Mother's age now = 3×12

= 36
