A. 279 hours
B. 271 hours
C. 275 hours
D. 280 hours
Solutions
Pipe A can empty a filled tank in 28 hours,
while Pipe B can fill the same tank, when empty, in 35 hours,
Let total work = LCM of (28, 35) = 140 units
Efficiency of Pipe A = 140/28 = – 5 units
Efficiency of Pipe B = 140/35 = 4 units
⇒ Pipe (A + B) 2 hour’s work = – 5 + 4 = – 1 unit
In 2 hours, both pipes can empty the 1 unit of tank.
Then in 270 hrs, they can empty = – 1 × 135 = -135 units
Remaining tank = 140 – 135 = 5 units
Then, pipe A will empty the tank in 1hr.
∴ Total hours = 271 hours

48. The number of free electrons in the outermost shell of carbon atoms in diamond is:
A. Zero
B. Two
C. Four
D. Three
Solutions
The electronic configuration of carbon= (2, 4). Therefore, the Valency of carbon is 4.
Carbon atom forms four covalent bonds with other carbon atoms in a diamond. This phenomenon is termed as catenation. Hence there areno free electrons in outmost shell of carbon.
The name ‘carbon’ is derived from the Latin word ‘carbo’ meaning coal. Carbon is found in nature in free as well as compound state.
49. 13 years ago, Ram was twice as old as Sunny. Three years from now Sunny’s age will be 3/5 of Ram’s age. What is Ram’s current age?
A. 64 years
B. 72 years
C. 80 years
D. 77 years
Solutions
13 years ago, Ram was twice as old as Sunny,
Let Ram be ‘R’ years old and Sunny be ‘S’ years old,
⇒ (R – 13) = 2(S – 13)
⇒ R – 13 = 2S – 26
⇒ 2S – R = 13
Three years from now, Sunny’s age will be 3/5 of Ram’s age,
⇒ (S + 3) = 3/5(R + 3)
⇒ 5S + 15 = 3R + 9
⇒ 3R – 5S = 6
Solving,
⇒ 3R – 5(13 + R) /2 = 6
⇒ 6R – 65 – 5R = 12
⇒ R = 77
∴ Ram present age is 77 years.
50. If the power of a corrective lens in +2.0D, then it is a:
A. Convex lens
B. Concave lens
C. Convex mirror
D. Concave mirror
Solutions
The correct answer is Convex lens.
- The capacity of a lens to converge or diverge incident rays is called its power (P). The unit of the power of a lens is Dioptre (D).
- Power is the inverse of its focal length (f). The power of a lens depends on its focal length.
- The focal length of a convex lens is positive thus the spectacles used to correct farsightedness has positive power.

61. A and B together can complete a task in 12 days. However, if A works alone, completes half the job and leaves and then B works alone and completes the rest of the work, it takes 25 days in all to complete the work. If B is more efficient than A, how many days would it have taken B to do the work by herself?
A. 18
B. 22
C. 20
D. 15
Solutions
Given,
(A + B)’s 1 day’s work = 1/12
⇒ 1/A + 1/B = 1/12
Given,
⇒ (A/2) + (B/2) = 25
⇒ A + B = 50
Solving,
⇒ 1/ (50 – B) + 1/B = 1/12
⇒ B2 – 50B + 600 = 0
⇒ B2 – 30B – 20B + 600 = 0
⇒ B(B – 30) – 20(B – 60) = 0
⇒ B = 30 or B = 20
If B = 30 Then A = 20
If B = 20 Then A = 30
But B is more efficient than A,
∴ B takes 20 days to complete the work.
