Each of the questions below consists of a statement and/or 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 a: if the data in Statement I alone are sufficient to answer the question, while the data in Statement II alone are not sufficient to answer the question.
Give answer b: if the data in Statement II alone are sufficient to answer the question, while the data in Statement I alone are not sufficient to answer the question.
Give answer c: if the data either in Statement I or in Statement II alone are sufficient to answer the question.
Give answer d: if the data even in both Statements I and II together are not sufficient to answer the question.
Give answer e: if the data in both Statements I and II together are necessary to answer the question.
(Caution : Do not hasten to mark the answer unless you consider both the Statements carefully).
Brinda’s merit rank is 17th in her class. What is her rank from the last ?
I. There are 70 students in her class.
II. Nisha who ranks 20th in Brinda’s class is 51st from the last.
Brinda's rank from top = 17th
I : There are 70 students in her class.
=> Brinda's rank from last = $$(70+1)-17=54$$
Thus, I alone is sufficient.
II : Nisha's rank from top = 20th and from last = 51st
Thus, total students in class = $$(51+20)-1=70$$
=> Brinda's rank from last = $$(70+1)-17=54$$
Thus, II alone is sufficient.
$$\therefore$$ Each statement alone is sufficient.
