Each of the builders can build the wall alone in 15 hours while any of the destroyers can demolish it in 10 hours. If all 20 builders and destroyers are made active when there is no wall and the wall get built in 3 hours, how many of them are destroyers?
A. 7
B. 5
C. 8
D. 6
Solutions
Let the total work be 30 units, (LCM of 15 and 10)
Each of the builders can build the wall alone in 15 hours while any of the destroyers can demolish it in 10 hours, and when they work together the wall gets built in 3 hours,
⇒ 1 hour work of Builder and Destroyer = 30/3 = 10 units
⇒ 1 hour work of Builder = 30/15 = 2 units
⇒ 1 hour work of Destroyer = 30/10 = -3 units
⇒ Difference between the work done = 10
Let the number of destroyers be x and number of builders be (20 – x),
⇒ 2(20 – x) – 3x = 10
⇒ x = 6
∴ Number of destroyers is 6.

A. 30
B. 40
C. 36
D. 32
Solutions
A can complete a task alone in 8 days, while B takes 12 days to do it by herself. Together with C it takes them 4 days to complete the work,
Let the total work be 24 units,
⇒ 1 day work of A = 3 units
⇒ 1 day work of B = 2 units
⇒ 1 day work of (A, B and C) = 6 units
⇒ 1 day work of C = 1 units
⇒ C takes 24 days to complete the work alone.
C and D together can complete the task in 15 days,
Let the total work be 120 units,
⇒ 1 day work of C = 5 units
⇒ 1 day work of (C and D) = 8 units
⇒ 1 day work of D = 3 units
∴ D takes 40 days to complete the work alone.

B. The magnitude of the force of attraction (or repulsion) between two-point charges is inversely proportional to the product of the quantity of the two charges and directly proportional to the square of the distance between them.
C. The magnitude of the force of attraction (or repulsion) between two-point charges is inversely proportional to the product of the quantity of the two charges as well as to the square of the distance between them.
D. The magnitude of the force of attraction (or repulsion) between two-point charges is directly proportional to the product of the quantity of the two charges and inversely proportional to the square of the distance between them.
Solutions
CONCEPT:
- Coulomb’s law: When two charged particles of charges q1 and q2 are separated by a distance r from each other then the electrostatic force between them is directly proportional to the multiplication of charges of two particles and inversely proportional to the square of the distance between them.
Force (F) ∝ q1 × q2
Where K is a constant = 9 × 109 Nm2/C2
EXPLANATION:
- Coulomb’s Law talks about the magnitude of the attraction between the two charges.
- It says that the force is directly proportional to the product of the quantity of the two charges and inversely proportional to the square of the distance between them. So option 4 is correct.

72. If ABCD is a trapezium, AC and BD are the diagonals intersecting each other at point O, then AC : BD is:
A. AB + AD : DC + BC
B. AB : CD
C. OA – OC : OB – OD
D. AD : BC
Solutions
O is the point where diagonals intersect,
AB ∥ CD
In ΔOAB and ΔOCD,
∠OAB = ∠OCD,
∠OBA = ∠ODC,
∠AOB = ∠COD,
⇒ ΔOAB and ΔOCD are similar,
⇒ OA/OC = OB/OD —-(1)
⇒ OA/OC + 1 = OB/OD + 1
⇒ AC/OC = BD/OD
⇒ AC/BD = OC/OD —-(2)
OA/OC = OB/OD = α (Let)
⇒ OA = αOC, OB = αOD
⇒ OA – OC = αOC – OC = OC(α – 1),
OB – OD = αOD – OD = OD(α – 1)
⇒ (OA – OC) / (OB – OD) = {OC(α – 1)}/{OD(α – 1)}
= OC/OD
∴ AC/BD = (OA – OC) / (OB – OD)
