Answer 1

Answer:

Answer is below

Step-by-step explanation:

Let racky age = X

Racky mother s age 4X

After 5 years

Racky s age = X+5

Racky s mother age = 4X+5

X+5 + 4X+5 = 3X+5

5X+10 = 3X + 5

5X-3X = 5-10

2X = -5

X = -2/5

therefore, racky s age is -2/5

Racky mother s age = 4X

= 4× -2/5

= 4/1 × -2/5

= 4×-2/5×1

= -8/5

• Present ages of Racky and her mother ?

$\blue{ \bigstar} \sf \: S \: O \: L \: U \: T \: I \: O \: N$

$\:$

• Firstly, let us consider that Racky's age be m years. So, her mom's age is 4m years.

• After 5 years Racky's age is (m + 5) years and her mother's age is (4m + 5) years.

$\:$

$\underline { \sf{ \bigstar \: According \: to \: the \: given \: Question \: :: }}$

$\\ \dashrightarrow \: \sf \: 3 \big(Age \: of \: racky \big) = Age \: of \: her \: mother$

$\\ \dashrightarrow \: \sf 3 \big(m + 5 \big) = 4m + 5$

$\\ \dashrightarrow \: \sf \big(3 \times m \big) + \big(3 \times 5 \big) = 4m + 5$

$\\ \dashrightarrow \: \sf \: 3m + 15 = 4m + 5$

$\\ \dashrightarrow \: \sf \: 15 - 5 = 4m - 3m$

$\\ \dashrightarrow \: \boxed{ \bf{ \pink{ \: m = 10}}} \: \green{ \bigstar}$

✇ Finding their present ages ::

$\:$
