Each of the questions given below consists of a question and two statements numbered I and II. You have to decide whether data provided in the statements are sufficient to answer the questions.
A’s and B’s Salaries are in the proportion of 4 : 3 respectively. What is A’s salary ?
I. B’s salary is 75% that of A’s salary.
I. B’s salary is Rs. 4,500.
Suppose A's salary is 4x and B's salary is 3x.
Statement 1: B's salary is 75% of that of A's salary. This statement is the same as the original statement since 75% equals 3/4. So, we dont get any valuable iformation from this statement.
Statement 2: B's salary is 4500 Rs.
Combining with original statement, 3x = 4500
Therefore, x = 1500
And 4x = 6000.
Hence, we get A's salary as Rs 6000.
So, the second statement is sufficient to get A's salary. Hence Option (B).
