x-5(swara)

2x-5(swati)

According to ques.

$2x - 5 = 3x - 15 \\ - x = - 15 + 5 \\ - x = - 10 \\ x = 10$

Swara Age is 10

Answer 2

Answer:

SWATI = 2x

SWARA = x

5 years ago

SWATI = 2x-5

SWARA = x-5

Q. Five years ago her age was three times Swara's age. Find their present age.

2x-5 = 3(x-5)

2x-5 = 3x-15

2x-3x = -15+5

-x = -10  [REMEMBER: (-) x (-) = (+)]

x=10

PRESENT:

SWATI = 2x = 2 x 10 = 20

SWARA = x = 10

Therefore; Swati is 20 years old and Swara is 10 years old at present.
