Answer: D) 17/20 Explanation: n(S) = 20n(Even no) = 10 = n(E)n(Prime no) = 8 = n(P)P(E U P) = 10/20 + 8/20 - 1/20 = 17/20

Answer: A) 25200 Explanation: Number of ways of selecting (3 consonants out of 7) and (2 vowels out of 4) =( C37×C24 ) = 210. Number of groups, each having 3 consonants and 2 vowels =210 Each group contains 5 letters. Number of ways of arranging 5 letters among themselves = 5! = 120.  Required number of words = (210 x 120) = 25200.

Answer: C) Both A & B Explanation: Geothermal power plants are used in order to generate electricity by the use of geothermal energy (the Earth's internal thermal energy). They essentially work the same as a coal or nuclear power plant, the main difference being the heat source. Geothermal power plants use hydrothermal resources that have both water (hydro) and heat (thermal). Geothermal power plants require high-temperature (300°F to 700°F) hydrothermal resources that come from either dry steam wells or from hot water wells.

The United States government has 3 branches, which all serve an important role in running the government and keeping our system of laws in place.   1. The legislative branch 2. The executive branch  3. The judicial branch   The legislative branch makes the laws while the executive branch enforces these laws.  The judicial branch is a system of courts that applies the laws.   Both the federal government and each of the 5 states have individual judicial branches which all serve this purpose.   For example ::  If the federal government were like a basketball game, the judicial branch is much like the referee that helps settle disputes. The executive branch and the legislative branch are often like the players in the game trying to score points against each other, and the judicial branch is there to clarify the rules and make sure each side is acting fairly.

Answer: B) 204 m Explanation: To find the minimum distance, we have to get the LCM of 75, 80, 85 Now, LCM of 75, 80, 85 = 5 x 15 x 16 x 17 = 20400 Hence, the minimum distance each should walk so that thay can cover the distance in complete steps = 20400 cms = 20400/100 = 204 mts.

Answer: B) Rs. 4826 Explanation: We know the formula for calculating The compound interest C = P1 + r100n - 1 where P = amount, r = rate of interest, n = time Here P = 5000, r1 = 10, r2 = 20 Then C = 65001 + 101002 x 1 + 201002 - 1= 6500 x 18562500= 65 x 185625 C = Rs. 4826.
