Marks: +1, -0

According to Sony, her age is greater than 33 years but less than 40 years. Her mother does not feel so and thinks that Sony's age is greater than 25 years but less than 38 years. However, her father thinks that she cannot be more than 36 years old. Assuming all of them to be correct, find out the average of different probable ages of Sony.

34.5 years
35.5 years
37 years
38 years

Solution:

Let Sony's age be x years.

According to Sony, 33 < x < 40

According to her mother, 25 < x < 38

According to her father, x < 36

Thus, her probable age can be 34 and 35 years.
