Question

the ratio of ages of Tina and her mother 4:6. At the time of birth her mother's age was 30 years find the present ages of Tina and her mother. ​

Answer 1

Given :

• Ratio of the age of Tina and her mother 4:6
• Her mothers age 30 years

To find :

• Present age of Tina and her mother

According to the question,

Let the ratio be 4x and 6x

→ 6x - 4x = 30

→ 2x = 30

→ x = 30 ÷ 2

→ x = 15

So,

Age of Tina :

→ 4x

→ 4(15)

→ 60 years

Age of Tina's Mother :

→ 6x

→ 6(15)

→ 90 years

So,

• Age of Tina is 60 years.
• Age of Tina's mother is 90 years.

Answer 2

Answer:

Step-by-step explanation:he ratio of Hari's and Harry's present ages is 5:7  

So, let their ages be 5x and 7x

After 4 years their ages will be in ratio 3:4

Therefore,(5x+4)/(7x+4)=3/4

or, 4(5x+4)=3(7x+4)

or, 20x+16=21x+12

or, 16−12=21x−20x

or, 4=1x

or, x=4

Therefore, present age of Hari = 5x=(5×4)=20 years.

Present age of Harry =7x=(7×4)=28 years

The sum of their age is 28+20=48years
