The following question consists of two statements I and II are given below. You have to decide whether the data provided in the statements are sufficient to answer the question.
What will be the average weight of the remaining class?
I. Average weight of 30 children out of total 46 in the class is 22.5 kg and that of remaining children is 29.125 kg. A child having weight more than 40 kg is excluded.
II. Average weight of class of 46 children is 23.5 kg. A child weighing 46 kg is dropped out.
(a) The data in statement I alone was sufficient to the answer the question while II alone not sufficient to the answer the question.
(b) Data in statement II alone are sufficient to answer the question while data in statement I alone are not sufficient to answer the questions.
(c) The data in statement I alone or in statement II alone are sufficient to answer the questions.
(d) The data in both statements I and II are not sufficient to answer the question.

(b) Data in statement II alone are sufficient to answer the question while data in statement I alone are not sufficient to answer the questions.
(c) The data in statement I alone or in statement II alone are sufficient to answer the questions.
(d) The data in both statements I and II are not sufficient to answer the question.
I. Total weight of 46 children= kg
= 1141 kg,
Weight excluded is not exact, so, average of remaining class cannot be obtained.
II. Total weight of 45 children = kg.
Average weight of 45 children = = 23 kg.
So, II alone gives the answer while I alone does not.
