A tennis player before playing a major tournament had a win ratio of 2 : 3. Win ratio is defined as the ratio of the number of matches won to the total number of matches played by a player. The player won 4 out of 5 matches played in the Australian Open and his win ratio after it is more than 69 : 100. What could be the maximum total number of matches played by the player including the matches played in the Australian Open?
A player has 20 average goals in 40 Hockey matches. In his next few matches, his average goals decreased by 1 and the total number of goals is increased by 55. Also, in the next 15 matches, the total number of goals is increased by 225 that he has in 40 matches. What will be his overall average after playing all the matches?
Following pie charts present the total runs scored by two teams A and B respectively against each other in the five one day matches. Total Runs Scored by Two Teams in 5 Matches If the total runs scored by the two teams A and B in 5 matches are 1800 and 1700, respectively then what is the number of matches won by team A out of the 5 given matches?
oil and kerosene are present in ratio of 5 : 7 in a liquid. Few litres of mixture of mixture are replaced with petrol. Ratio of oil : kerosene: petrol is 35 : 49 : 18 respectively. Amount of oil removed from mixture is 21 litres less than that of petrol added to the mixture. And amount of oil removed is 6 litres less than that of difference mentioned. Petrol is replacing the mixture removed hence; quantity of mixture is not changing. What is the difference between quantity of kerosene in old mixture and amount of oil in new mixture?

A solid-oxide fuel cell is fed with carbon monoxide and reacts with air to produce CO2. This reaction will produce 2 electrons which are used to power an electric circuit external to the fuel cell. The reaction equation is shown below: 2CO(g) + O2(g) -> 2CO2(g) ΔHr° = -565.96 kJ/mol This reaction does not occur for other types of fuel cells which use a catalyst, such as polymerelectrolyte membrane or phosphoric-acid fuel cells. The presence of carbon monoxide on the anode side of these types of fuel cells will cause catalyst poisoning, reducing the efficiency and voltage of the fuel cell. Determine the rate of enthalpy change for a carbon dioxide production rate of 208 mol/hr. The extent of the reaction occurring in the fuel cell can be obtained by the following equation: where:
