Q89 · Logical Reasoning & Mathematics

In the figure given below, PQR is a triangle. QR is parallel to PM. If QR=PR, then what is the value of ∠RPM?

Triangle PQR with Q at the top left, R at the right and P at the bottom; the angle at Q is marked 50°. A line from R meets side QP at a point where the angle below it is marked 95°. Through P runs a line with arrows at both ends, the right end labelled M.
  1. (1)70°
  2. (2)80°✓ Correct answer
  3. (3)100°
  4. (4)95°

Explanation

In the figure ∠PQR = 50°. Since QR = PR, ∠RPQ = ∠RQP = 50°, so ∠QRP = 180° − 100° = 80°. QR ∥ PM, so ∠RPM = ∠QRP = 80° (alternate angles); the 95° mark is not needed.

Q90 · Logical Reasoning & Mathematics

  2. (2)Trapezium
  3. (3)Square
  4. (4)Rhombus✓ Correct answer

Explanation

AB, BC, CD and DA all have length √388, so the four sides are equal. But AB·BC = (−18)(−8) + (−8)(−18) = 288 ≠ 0, so the angles are not right angles: it is a rhombus, not a square.

Q94 · General English

Read the passage and answer the questions that follow by choosing the appropriate answer : (Q. 94 to 98) Once we have settled on a perspective, we close off with one line of thought. Certain kinds of ideas occur to us, but only those kinds and no others. What if the crippled man who invented the motorized cart had defined his problem as, “How to occupy my time while lying in bed?” rather than “How to get out of bed and move around the house?” Leonardo Da Vinci believed that to gain knowledge about the form of problems, you begin by approaching the problem on its own terms. He felt the first way he looked at a problem was too biased towards his usual way of seeing things. He would restructure his problem by looking at it from one perspective and move to another perspective and still another. With each move, his understanding would deepen and he would begin to understand the essence of the problem. Da Vinci discovered that genius often comes from finding a new perspective that no one else has taken. Albert Einstein was once asked what the difference was between him and the average person. He said that if you asked the average person to find a needle in the haystack, the person would stop when he or she found a needle. He, on the other hand, would tear through the entire haystack looking for all the possible needles. With creative thinking, one generates as many alternative approaches as one can. Most of us have been educated to think exclusively which means we think in deficit by focusing our attention on specific information and excluding all else. In these instances, exclusive thinking leads us to neglect potentially important pieces of the puzzle. Exclusive thinking doesn’t merely inhibit irrelevant facts and perceptions. It can also smother the imagination. Creative thinking is inclusive thinking. You consider the least obvious as well as the most likely approaches, and you look for different ways to look at the problem. It is the willingness to explore all approaches that is important, even after one has found a promising one. Identify statements which are true with respect to the passage: a. Our settled perspective towards a problem makes us focus on one line of thought only. b. Leonardo Da Vinci always solved a problem in the first attempt . c. Albert Einstein would look for as many alternatives as he could to solve a problem. d. Exclusive thinking enhances creativity and imagination.

  1. (1)a and b only
  2. (2)b and c only
  3. (3)a and c only✓ Correct answer
  4. (4)c and d only

Explanation

(a) matches 'we close off with one line of thought' and (c) matches Einstein searching the whole haystack. (b) is wrong: Da Vinci distrusted his first view; (d) is wrong: exclusive thinking smothers imagination.

  3. (3)0.4655
  4. (4)1.5345

Explanation

This question was deleted by RSSB in its final answer key. A likely reason: the root sign was printed over the whole expression; the intended √(4a² − 4a + 1) + 3a = (1 − 2a) + 3a = 1 + a = 1.1069, but as printed √(4a² − a + 1) ≈ 0.969, which is not among the options.
