Answer : 1. "Thermosphere"
Explanation :
Answer: A) Thermosphere Explanation: In terms of the Earth's atmosphere, they occupy regions called the thermosphere and the exosphere. The layer through which a satellite orbits depends on the satellite's function and the kind of orbit it has. The thermosphere is a region of very high temperature that extends from the top of the mesosphere at around 85 kilometers (53 miles) up to 640 kilometers (400 miles) above the Earth's surface. It is called the thermosphere because temperatures can reach up to 1,500 degrees Celsius (2,732 degrees Fahrenheit). However, despite the high temperatures, the pressure is very low, so satellites don't suffer heat damage.
Q: K and L start the business, with L investing the total capital of Rs. 40,000 on the condition that K pays L interest @ 8% per annum on his half of the capital.

Answer : 2. "Rs.46400"
Explanation :
Answer: B) Rs.46400 Explanation: Interest received by L from K = 8% of half of Rs.40,000 ⇒8100×20000=1600 Amount received by L per annum for being a working partner = 1200 x 12 = Rs.14,400 Let 'A' be the part of remaing profit that 'L' receives as his share. Total income of 'K' = only his share from the reamaing profit = 'A', as both share equally. Given income of L = Twice the income of K --> (1600 + 14400 + A ) = 2A --> A= Rs.16000 Thus total profit = 2A + Rs.14,400= 2(16000) + 14400 = 32000 +14400 = Rs.46,400.
