ii) 7x.

iii) 2y + 3 = 11.

iv) 2p < 7.

10. Your answer is option iii)

Question -:

11. Raju's father's age is 2 years more than 3 times Raju's age. If Raju's present age is y years, then what is his father's age?

Answer -:

Raju's age is y years.

Three times Raju's age = 3y years.

The age or Raju's father is 2 years more than three times Raju's age.

Thus, his father's age is -: 3y + 2 years.

Thus, the age of Raju's father is -:

3y + 2 years.

The answer is in the form of a variable because you cannot form an equation here.

Hope it helps you and is correct! Sorry if its wrong! :)
