Question

the present age of swapna's father is 2 times that of swapna.After 10 years the sum of their ages would be 65. find there present ages​

Answer 1

Let, swapna's at be = x

swapna's father's age be =2x (it is said In the question that swapna's father's age is 2 times her age)

AFTER 10 YEARS

SWAPNA'S AGE =X+10

SWAPNAS FATHER'S AGE =2X+10

SUM OF THEIR AGES =65

SO,

X+10+2X+10=65

3X+20=65

3X=65-20

3X=45

X=45/3

X=15

THEREFORE, SWAPNA'S AGE IS 15YRS AND HER FATHERS AGE = 15*2=30

Answer 2

Answer:

• Swapna's age = 15 years
• Swapna's father age = 30 years

Step-by-step explanation:

Given:

• Present age of Swapna's father is 2 times of Swapna's age.
• After 10 years the sum of their ages = 65

To Find:

• Present ages of Swapna and her father.

Let, Present age of Swapna be 'x'.

And, present age of Swapna's father be '2x'.

✦ After 10 years:

➜ x + 10 + 2x + 10= 65

➜ 3x + 20 = 65

➜ 3x = 45

➜ x = 45/3

➜ x = 15

✦ Swapna age = 15 years.

✦ Swapna's father age = 2 × 15 = 30 years.
