- C.
34 și 36;

The correct answer is 34 and 36. This is because when you add two consecutive even numbers, the result will always be an even number. Therefore, options 33 and 37, as well as options 32 and 38, are incorrect because they contain odd numbers. Option 34 and 35 is also incorrect because the numbers are not consecutive. Only option 34 and 36 satisfies the condition of adding two consecutive even numbers to equal 70.Rate this question:

Horia are 12 ani și este cu 7 ani mai mic decât Nicușor. Peste 2 ani, băieții vor avea împreună:
- A.
21 de ani;
- B.
31 de ani;
- C.
33 de ani;
- D.
35 de ani.
Correct Answer
D. 35 de ani.Explanation
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.Rate this question:
