  2. Statement (b) ALONE is sufficient to answer the question, but statement 1 alone is NOT sufficient. 
  3. BOTH statements (a) and (b) TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient.

By how much percentage has the Total surface area has increased of a Cylinder?

  1. Lateral Surface Area has increased by 10 %
  2. Curved Surface Area has increased by 20%

Discuss
+

Explanation: The rule is if two thing are getting added up and u don’t know their values , u would never be able to determine the percentage change in its total surface area. If two things are multiplied and then u can evaluate their percentage change even without knowing their values.

xyz is a three digit no. You reverse  that number and subtract it from the original number. What is result of this operation?

  1. The result is divisible by 11 and is a three digit number.
  2. The result consists of the same three digits as xyz and zyx.

Discuss
+

Explanation: There is only one three digit no. that can get such a result . 954 - 459 = 495.

Q #9
⏰ :

Logical Question

Directions: Each question is followed by two statements.

You have to decide whether the information provided the statements is sufficient for answering the question.

  1. Choose 1. If the question can be answered by using one of the statements alone, but cannot be answered by using the other statement alone.
  2. Choose 2. If the question can be answered by using either statement alone.
  3. Choose 3. If the question can be answered by using both the statements together, but cannot be answered by using either statement alone.
  4. Choose 4. If the question cannot be answered even by using both the statements together.

What is the area of the cyclic quadrilateral ABCD, where AB = 6 cm?

  1. AD and AB are equidistant from the centre of the circle.
  2. AB is parallel to CD and AB = CD.

Discuss
+

Explanation: From statement A, Let O be the centre of the circle. Given OE = OF ………..(1) where E and F are the foot of the perpendiculars drawn from AD and AB respectively. The given condition is possible only when ABCD is a square and AB = 6. So, the area of ABCD can be calculated. • A alone is sufficient. From statement B alone, since AB is parallel and equal to CD, ABCD is a rectangle. We do not have any information about the AD or BC. So, B alone is not sufficient.

Logical Question

Directions: Read the rules listed below.

  1. Statement (a) ALONE is sufficient to answer the question, but statement 2 alone is NOT sufficient. 
  2. Statement (b) ALONE is sufficient to answer the question, but statement 1 alone is NOT sufficient. 
  3. BOTH statements (a) and (b) TOGETHER are sufficient to answer the question, but NEITHER statement ALONE is sufficient. 
  4. Each statement ALONE is sufficient to answer the question. 
  5. Statements (a) and (b) TOGETHER are NOT sufficient to answer the question.

  1. If the question can be answered by using one of the statements alone, but cannot be answered using the other statement alone.
  2. If the question can be answered by using either statement alone.
  3. If the question can be answered by using both statements together, but cannot be answered by using either statement alone.
  4. If the question cannot be answered based on the information provided 

Is the prime number p equal to 37?

  1. p = n^2 + 1, where n is an integer   
  2. p^2 is greater than 200

Discuss
+

Explanation: Since 142 = 196 and 152 = 225, if follows from (B) that p > 14 In (A) the expression n2 + 1 can represent a prime number less than 37, equal to 37, or greater than 37, depending on the value of n. For example, if n = 4, the 42 + 1 = 17; if n = 6, then 62 + 1 = 37; if n = 10, then 102 + 1 = 101; and 17, 37, and 101 are all prime numbers. Thus, (A) alone is not sufficient Both the statements together are not sufficient
