Answer: 30
Step-by-step explanation:
Let, he gave x correct answer.
Since, He gets 2 stars for every 5 correct answer.
⇒ For 5 correct answers number of stars = 2
⇒ For 1 correct answer number of stars = [tex]\frac{2}{5}[/tex]
⇒ For x correct answer number of stars = [tex]\frac{2x}{5}[/tex]
According to the question,
He want to get 12 stars,
⇒ [tex]\frac{2x}{5}=12[/tex]
⇒ [tex]2 x = 60[/tex]
⇒ [tex]x = 30[/tex]
Thus, the minimum number of correct answer is 30.
