Consider the following question and decide whether the statements are sufficient to answer the question. Question: In a box, there are packets of three different sizes. How many packets are there in the box? Statements: 1. Half of all the packets are of medium size. 2. There are six big packets. 3. There are twice the amount of small packets than there are big packets. Correct Answer Statement 1, 2 and 3 together are sufficient
According to the given information,
Statement 1: This statement alone is insufficient since we cannot determine the number of packets.
Statement 2: This statement alone is also insufficient since information of about big packets is only given in this statement.
Statement 3: This statement alone is also not sufficient, since information about smaller and larger packets is only given in this statement.
Combining the three,
From statement 2, there are 6 big packets.
From statement 3,
There are twice the amount of smaller packets than there are larger packets.
And,
From statement 1, it is mentioned that half of all packets are the medium packets.
Combining all the three, we can find the number of packets in the box.
Hence, “statement 1, 2 and 3 together” are sufficient.
