Answer 2

Answer :

age of his sister is 36 year

Step-by-step explanation:

It is given that Amit's and his sister's age are in the ratio 5 : 4

let us assume that Amit's age is 5x and his sister's age 4x

And also we have given that Amit's age is 45 year

So, 5x = 45

x = 45/5

x = 9

put the value of x in the assumes ratio

5x = 5*9 = 45 ( as we have given )

4x = 4*9 = 36 ( as we found above )

Hence, the age of his sister is 36 year
