A metal pipe is 14 cm long with outer radius 4 cm and inner radius 3 cm. What volume of metal does it contain? (Take π = 22/7)
सही उत्तर: ख) 308 cm³
V = π(R² − r²)h = (22/7)(16 − 9)(14) = 308 cm³.

Water flows at 5 m/s through a pipe of internal radius 7 cm. How long will it take to fill a tank of 46,200 litres? (Take π = 22/7)
सही उत्तर: ग) 10 minutes
Flow = 154 cm² × 500 cm/s = 77,000 cm³/s = 77 L/s = 4,620 L/min; 46,200/4,620 = 10 minutes.

A copper rod of diameter 2 cm and length 18 cm is drawn into a uniform wire of diameter 2 mm. What is the length of the wire?
सही उत्तर: घ) 18 m
Volume is unchanged: π(1)²(18) = π(0.1)²L, so L = 1,800 cm = 18 m.

A bucket is a frustum of a cone with top radius 6 cm, bottom radius 3 cm and height 7 cm. What is its volume? (Take π = 22/7)
सही उत्तर: ख) 462 cm³
V = πh/3 (R² + Rr + r²) = (22/7)(7/3)(36 + 18 + 9) = 462 cm³.

Assuming each day of the week is equally likely, what is the probability that four randomly chosen people were all born on different days of the week?
सही उत्तर: घ) 120/343
(7 × 6 × 5 × 4)/7⁴ = 840/2401 = 120/343.

In a game you win Rs. 100 with probability 0.2 and lose Rs. 20 otherwise. What is your expected gain per game?
सही उत्तर: ग) Rs. 4
E = 0.2 × 100 − 0.8 × 20 = 20 − 16 = Rs. 4.

Three independent events have probabilities 0.5, 0.4 and 0.2. What is the probability that at least one of them occurs?
सही उत्तर: क) 0.76
P(none) = 0.5 × 0.6 × 0.8 = 0.24, so P(at least one) = 0.76.

Machine A makes 60% of a factory's output with 2% defectives, and machine B makes the rest with 3% defectives. What is the probability that a randomly chosen item is defective?
सही उत्तर: घ) 0.024
0.6 × 0.02 + 0.4 × 0.03 = 0.012 + 0.012 = 0.024.
