Answer 1

Answer:

Komal = 20 years old

Mother = 40 years old

Step by Step explanation:

Define x:

Let Komal be x years old

Mother = 2x

Find their age 10 years ago:

Komal = x - 10

Mother = 2x - 10

Solve x:

Mother was thrice as old as Komal

2x - 10 = 3(x - 10)

2x - 10 = 3x - 30

x = 20

Find their present age:

Komal = x = 20 years old

Mother = 2x = 2(20) = 40 years old

Answer: Komal is 20 years old and Mother is 40 years old

Answer 2

$<b><I>$Heyaaa mate

The answer is:-

Let us consider komal's age be x

so,

ATQ,

Her mother's age will 2x.

10 years ago

Komal's age = $x - 10$

Her mother's age = $2x - 10$

Therefore,

$2x - 10 = 3(x - 10)$

=>$2x - 10 = 3x - 30$

=> $2x - 3x = -30 +10$

=> $-x = -20$

=> $x = 20$years

Now 2x will be,

$2x = 2(20) = 40$years

Hence,

Her present age is 20 years and her mother's present age is 40 years .

Hope it helps you
