Direction (11-15): In the given questions, two quantities are given, one as ‘Quantity 1’ and another as ‘Quantity 2’. You have to determine relationship between two quantities and choose the appropriate option:
(a) Quantity 1 > Quantity 2
(b) Quantity 1 ≥ Quantity 2
(c) Quantity 2 > Quantity 1
(d) Quantity 2 ≥ Quantity 1
(e) Quantity 1 = Quantity 2 or Relation cannot be established

Q11. Quantity 1: Find the speed of train (in m/s) if the train takes 20 sec to completely cross another train coming from opposite direction of twice the length & speed both as that of first train. The first train can cross a platform 100 m long in 30 sec.
Quantity 2: Find the speed of train (in m/s) if the train overtakes another train running at a speed of 20 m/s in 70 sec while the latter train can cross a platform of same length in 25 sec. Length of first train is 60% less than that of latter train. (latter train is faster)

Q12. Quantity 1: Find the number of blue balls in the bag if the probability of getting a red ball when 3 balls are drawn at random from the bag having 15 balls is 45/91. If there would be no blue balls, this probability would be 5/11. The bag contains red, blue & green color balls and the blue balls are minimum in the bag.
Quantity 2: Find the number of blue balls in the bag if the bag contains ‘x’ red balls & ‘y’ blue balls such that x²-3x-10=0 and probability of drawing 2 red balls from the bag at random is 2/9.

Q13. Quantity 1: Find the value of (a+b-c)² if(a+b)²=25=b²+c²; a < b < c & a, b, c ∈ N
Quantity 2: Find the value of (a+b-c)² if a :b=1:1; a is 40% less than c and average of b & c is 4.

Q14. Quantity 1: In what time (min) the tank will be filled completely if all the pipes are opened simultaneously. There are 3 pipes of which 2 are inlet and other is outlet. If there is only 1 inlet (which is the most efficient), then tank will be filled by both the pipes in 30 min. The inlet pipes alone take 10 & 12 min respectively to fill the tank. All pipes are opened till tank is filled.
Quantity 2: In what time (min) the tank will be filled completely if all the pipes are opened simultaneously. Pipe A, B & C alone can fill the tank in 15, 12 & 10 min respectively. Pipes are opened in a pair for a minute & no pipe works for more than 2 min continuously. (consider minimum time taken)

Q15. Quantity 1: Curved surface area of sphere is 616 sq.m. Find curved surface area of cylinder (sq.m.) if the sphere is melted to form a cylinder of height 28/3 m.
Quantity 2: Curved surface area of sphere is 616 sq.m. Find curved surface area of cylinder (sq.m.) if the cylinder can completely fit inside the sphere such that top & bottom of cylinder lies on surface of sphere. Radius of cylinder = 7 m.
