the first option is the answer
Step-by-step explanation:
4c + 6a <= 120 [building hours]
4c + 4a <= 100 [testing hours]
4 * 20 + 6 * 6 <= 120
80 + 36 <= 120
116 <= 120
true, they have enough building hours
4 * 20 + 4 * 6 <= 100
80 + 24 <= 100
104 <= 100
false, they won't have enough testing hours

<h3>Answer :- </h3>
<h3>Solution :- </h3>
- Let the age of victor be X .
- and, the age of Mr.Smith be = 81 + x
♧ <em>So, after 3 years = x+81 +3</em>
- 81 + 3 + x = 4 ( x + 3 )
- 84 + x = 4x + 12
♧ <em>now grouping the variables and constants together we get,</em>
- 4x-x=84-12
- 3x = 72
- x = 72/3
- x = 24
♧ <em>Thus, Victor's present age is 24 yrs.</em>
