Answer : 2. "535"
Explanation :
Answer: B) 535 Explanation: The number of points of intersection of 37 lines is C237. But 13 straight lines out of the given 37 straight lines pass through the same point A. Therefore instead of getting C213 points, we get only one point A. Similarly 11 straight lines out of the given 37 straight lines intersect at point B. Therefore instead of getting C211 points, we get only one point B. Hence the number of intersection points of the lines is C237-C213-C211 +2 = 535

Answer : 4. "None of the statements is required"
Explanation :
Answer: D) None of the statements is required Explanation: From the given data, (60 - 45)% = 12.5 + 415% = 16.5=> 100% = ?100% = 16.5 x 100/15 = 110 Hence, P = 45% of 110 = 45x110/100 = 49.5 Q = 50% of 110 = 55R = 60% of 110 = 60 x 110/100 = 66M = 12.5 + 49.5 = 62 or 66 - 4 = 62 Hence, no statement is required to answer.

Answer : 2. "32 sec"
Explanation :
Answer: B) 32 sec Explanation: Given that, 1st train speed = 62 km/hr 2nd train speed = 44 km/hr Hence the relative speed of two trains is : 62-44 = 18 km/hr = 18×518 m/s = 5 m/s. There fore, the first train crosses the second train i.e (85+75)mts of distance with a speed of 5m/s in, time = distancespeed = 85+755 = 32 sec.
