Question

5 years ago, the sum of the ages of Kareena and Seema was 70 years and their ages
were in the ratio 3:4. Find the ratio of their present ages.​

Answer 1

Step-by-step explanation:

3x + 4x = 70

7x = 70

x = 70/7

x = 10

3x = 3 × 10

= 30

4x = 4 × 10

= 40

present age = 40 + 5 ; 30 + 5

= 45 ; 35

ratio = 35 : 45

= 7 : 9

Answer 2

Answer:-

Given:-

• The sum of the ages of Kareena and Seema was 70 years

• Their ages were in ratio 3:4

To find:-

• The ratio of their present ages

Solution:-

Let,

Kareena age = 3x

Seema age = 4x

⇒3x + 4x = 70

⇒7x = 70

⇒x = 70/7

⇒x = 10

5 years ago:

Kareena's age = 3×10

⇒30 years

Seema's age = 4 × 10

⇒40 years

Then,

The present ages:

Kareena's age = 30 + 5

⇒35 years

Seema's age = 40 + 5

⇒45 years

Then, the ratio of their present ages = 35/45 ⇒7/9⇒"7:9"
