21 de ani;

31 de ani;

33 de ani;

35 de ani.

Horia is currently 12 years old and is 7 years younger than Nicușor. In 2 years, both boys will be 2 years older. So, Horia will be 14 and Nicușor will be 19. Adding their ages together, we get 14 + 19 = 33. Therefore, in 2 years, the boys will have a combined age of 33 years. However, the question asks for their combined age in the future, not in 2 years. Therefore, we need to add 2 more years to their combined age, which gives us 33 + 2 = 35. Hence, the correct answer is 35 years.

60

70

50

80

The question states that the number is obtained by subtracting the reverse of 63 from a certain number and then subtracting the smaller neighbor of 29 from the result. Finally, the smallest number of tens is added to the obtained result to get the largest number smaller than 17. The only option that satisfies these conditions is 70.
