Answer 1

Answer:

(a) 20

Step-by-step explanation:

let their ages be 5x 7x and 9x

if 9x = 36

x = 36 ÷ 9

= 4

age of Sansa = 5x or 5 × 4

= 20

Answer 2

Answer:

The age of Sansa is 20 years.

Step-by-step explanation:

Given,ratio of the ages of Sansa,Sarah,Samantha is 5:7:9.

Let age of Sansa be 5x years

and age of Sarah be 7x years and age of Samantha be 9x years.

Now it is given that age of Samantha age is 36 years old.

So according to question,

$9x = 36 \\ x = \frac{36}{9} \\ x = 4$

So, value of x is 4.

Age of Sansa is (5×4) = 20 years and age of Sarah is (7×4) = 28 years and age of Samantha is (9×4) = 36 years.

Hence required age of Sansa is 20 years.
