Answer: C) Wind Explanation: The energy sources that are constantly being replenished, such as sunlight, wind, and water. This means that we can use them as much as we want, and we do not have to worry about them running out. Additionally, renewable energy sources are usually much more environmentally friendly than fossil fuels. Overall, they release very few chemicals, like carbon dioxide, that can harm the environment. Most of this energy comes from fossil fuels, such as coal, oil, and natural gas. These are nonrenewable energy sources, which means that if we use them all up, we can never get more during our lifetime. Fossil fuels also contribute greatly to global climate change by releasing carbon dioxide into the air when they are burned.

Answer: B) production of ATP from the breakdown of glucose Explanation: The three steps within the aerobic respiration process are glycolysis, the citric acid cycle, and oxidative phosphorylation. Photosynthesis builds glucose, and what was built in photosynthesis is broken down during aerobic respiration.   Hence, production of ATP from the breakdown of glucose is the main result of aerobic respiration.

Answer: C) 41 sec Explanation: Speed = 44 kmph x 5/18 = 110/9 m/s We know that, Time = distance/speed Time = (360 + 140) / (110/9) = 500 x 9/110 = 41 sec.

Answer: B) 13500 Explanation: Given in municipality election 54% votes have won by 1080   Let the total number of votes be x.    54x100 - 46x100 = 1080   8x = 108000   x = 13,500   Therefore, total number of votes = 13,500.

Answer: C) 32640 Explanation: We know that zero can't be in hundreds place. But let's assume that our number could start with zero.   The formula to find sum of all numbers in a permutation is   111 x no of ways numbers can be formed for a number at given position x sum of all given digits   No of 1 s depends on number of digits   So,the answer us   111 x 20 x (0+1+2+3+4+5) = 33300   We got 20 as follows. If we have 0 in units place we can form a number in 4*5 ways. This is for all numbers. So we have substituted 20 in formula.   Now, this is not the final answer because we have included 0 in hundreds place. so we have to remove the sum of all numbers that starts with 0.   This is nothing but the sum of all 2 digits numbers formed by 1 2 3 4 5. Because 0 at first place makes it a 2 digit number.   So the sum for this is 11 x 4 x (1+2+3+4+5). =660   Hope u understood why we use 4. Each number can be formed in 4x1 ways   So, the final answer is 33300-660 = 32640

Answer: A) 400 Explanation: 1st day the girl read = 40% 2nd day she read = 34 % Remaining percentage of book = 100% - (40% +34%) = 26% But given last two days she read equal number of pages => Each day she read 26%/2 = 13% Last day she read 52 pages = 13% 13% = 52 1% = 4 => 100% = 400 Total pages in the book is 400.
