Question
How many boys are there in the class? I. The
number of girls is 30% of the number of boys. II. The ratio of the number of boys to that of girls is 3:5. Each of the following questions below consists of a question and two statements numbered I and II given below it. You have to decide whether the data provided in the statements are sufficient to answer the question. Read both the statements and give answer.Solution
From I G = 30/100 B ∴ 10B = 3G From II B/G = 3/5 ∴ 5B = 3G. Hence, both are not sufficient to answer the question.
