Answer: C) 85 Explanation: Since the numbers are co-prime, they contain only 1 as the common factor.Also, the given two products have the middle number in common.So, middle number = H.C.F of 551 and 1073 = 29;First number = 551/29 = 19Third number = 1073/29 = 37.Required sum = 19 + 29 + 37 = 85.

Answer: B) Sun Explanation: The water cycle is a term for the movement of water between the Earth's surface, the sky and underground. Water evaporates due to heat from the sun. Hence, the water cycle is driven primarily by the energy from the sun. This solar energy drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil. Other water moves from plants to the atmosphere through the process of transpiration.

Answer: C) 2.5 Explanation: Bond Order  = 1/2[ Nb - Na] where Nb = Number of electrons in bonding molecular orbitals. Na = Number of Electrons in antibonding molecular orbitals   Bond Order of N2⁺: Total number of electrons: 13 Electronic Configuration= :σ1s² σ*1s² σ2s² σ*2s² π 2py² [π2pz² σ2px1 ] Bond Order = [9-4]/2 = 5/2 = 2.5.

Feudalism was the dominant social system in medieval Europe, in which the nobility held lands from the Crown in exchange for military service, and vassals were in turn tenants of the nobles, while the peasants were obliged to live on their lord's land and give him homage, labour, and a share of the produce, notionally in exchange for military protection. Feudalism was a combination of legal and military customs in medieval Europe that flourished between the 9th and 14th centuries.Feudalism was based on the division of land by the king to nobles and vassals in return for their military service under the Feudal Levy. The land was the main source of the economy and was dependent on the peasants who worked on the land. The reasons for the decline of Feudalism during the Medieval period of the Middle Ages included: The Crusades and travel during the Middle Ages opened new trade options to EnglandEngland started to move from land-based economy to a money-based economy.   The Black Death - this reduced the population of England by one third. Labour became a valuable commodity.   The Peasants Revolt - Peasants realized their worth and demanded changes. Charters were granted but ignored by nobles.   More trade saw the growth of more towns.   Peasants moved away from the country into towns they were eventually allowed to buy their freedom.   The land was rented and the rights of lords over labor decreased. Armed men were paid a wage and Medieval warfare was financed by taxes and loansNobles became weaker - the Kings took back their lands and power.   A centralized government was established.

Answer: A) 7:1 Explanation: Maneela lent Rs. 8000 in two parts,

Answer: B) 40 Explanation: Remaining work = 1 - 9/10 = 1/10   => A & B together completes 1/10 of work in 4 days   => 1 work can completed in ------ ? days   Let it be x days   =>  4110=x1   => x = 40 days.   Hence, A & B together can complete the work in 40 days.

Answer: D) 3:2 Explanation: Let he mixes the oils in the ratio = x : y Then, the cost price of the oils = 60x + 65y Given selling price = Rs. 68.20 => Selling price = 68.20(x+y) Given profit = 10% = SP - CP => 10/100 (60x + 65y) = 68.20(x+y)-(60x + 65y) => 6x + 6.5y = 8.20x + 3.20y =>2.2x = 3.3y => x : y = 3 : 2

Answer: C) 12% Explanation: Let the interest rate be r% We know that, S.I = PTR/100 => (1540 x 5 x r)/100  +  (1800 x 4 x r)/100 = 1788 => r = 178800/14900 = 12%
