Answer 1

Answer:

4 yrs ago

let res.yrs. 4x and 9x

age of tina

4x+10-----------(1)

9x-10--------------(2)

4x+10=9x-10

5x=20

x=4

age of tina 4 years ago was 16+10

26

age of tina after 4 years is 26+4

=30

Answer 2

answer is 3) 30 years

As ratio of ram's age 4 years ago: sonu's age

4 years ago is 4 :9,

Ram's present age = (4x + 4) years

Sonu's present age = (9x + 4) years

According to the question,

4x + 4 + 10 = 9x + 4 - 10

=> 4x + 14 = 9x - 6

=> 9x - 4x = 14 + 6 => 5x = 20

=> x = 4

Therefore, Tina's present age = 4x + 14

= (4*4)+14 = 30 years
