Question
In a queue of 90 people, Ms. Braganza is 23rd from the
right and Ms. Margaret is 28th from the left. How many people are there between Ms. Braganza and Ms. Margaret?Solution
Total number of people in the queue = 90 Position of Ms. Braganza from the right = 23 Position of Ms. Margaret from the left = 28 Thus, number of people between them = 90 – (23 + 28) = 90 – 51 = 39 Hence, the correct answer is (B).
