Each Of the questions below consists of 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 11 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 sullicient to answer the question.
Give answer c: if the data either in statement I alone or in statement II alone are sufficient to answer the question.
Give answer d: if the data given in both the statements I & II together are not sufficient to answer the question. and
Give answer e: if the data in both the statements I & II together are necessary to answer the question
How many children are there in the row ?
I. Manoj is twelfth from the left end and fourth to the left of Hari in that row.
II. Hari is eighth from the right end of that row.
NOTE :- Position from left end + Position from right end = Total students + 1
I : Manoj is 12th from left end and 4th to the left of Hari.
=> Hari's position from left end = 12+4 = 16th
We did not know the total no. of students from this.
Thus, I alone is not sufficient.
II : Hari's position from right end = 8th
We did not know the total no. of students from this.
Thus, II alone is not sufficient.
I & II : Combining the above two conditions, we get
Hari's position from left = 16th and from right = 8th
=> Total students = 16+8-1 = 23
Thus, I & II together are sufficient.
