A and B are two friends, together they go out for shopping. A buys a hat and a suit,all together A spends 15 rupees. B buys a hat which costs same as the suit bought byA. B even buys a dress which cost her one rupee less than the cost of hat bought by A.B says to A that "If at all I had bought my hat by spending one and half times the money u spent on buying your hat, we both would have spent the same amount on buying our items(together, i.e., 15 rupees).(a) what is the cost of hat bought by Lets say A spent x and y rupees on hat and suit respectively. from the conditions we can say B spent y and x-1 rupees on hat and dress respectively. From what B told to A we can write that.....=> x + y A man wearing a hat stands on a bridge across a river. At an instant his hat falls into the river and starts flowing along with the stream at the same speed of the stream.At the same instant the man jumps into the river and starts swimming in the directionopposite to the stream, like that he swims for 10 minute , then he turns back and starts swimming in the direction of the stream to retrieve the hat. He retrieves the hatunder another bridge which is 1000 yards away down the stream from the first Let the swimming speed of man be = a yds/min.speed of stream = b yds/min.Then the man swims at (a-b) yds/min. against the stream.and (a+b) yds/min in direction with the stream.Lets assume the man covered A train travels at a particular speed for a duration of one hour, after which one of its engine malfunctions reducing its speed to 3/5th of the actual speed before theoccurrence of fault in engine. It travels at this speed for 2 hours to reach at itsdestination. If the fault had occurred 50 miles later on, the train would have reachedits destination 45 minutes early. Find the distance traveled by the train. Let the actual speed of train be X miles/hour. after fault its speed will be reduced to 3X/5 miles/hour. If we could find the speed of the train, we will get the solution!!!by seeing one can find that Monkeys and bananas:Suppose 8 monkeys take 8 minutes to eat 8 bananas.(a) How many minutes would it take 3 monkeys to eat 3 bananas?Sol:each mky takes 8 min to eat a banana (b) How many monkeys would it take to eat 48 bananas in 48 minutes 8m=48 m=6 Glenn and Jason each have a collection of cricket balls. Glenn saidthat if Jason would give him 2 of Glenn and Jason each have a collection of cricket balls. Glenn saidthat if Jason would give him 2 of his balls they would have an equalnumber; but, if Glenn would give Jason 2 of his balls, Jason would have 2times as many balls as Glenn. How many balls does Jason have? 1. G+2=j-22. 2(G-2)=J+2.solve these 2 to getJ=14 A rich merchant had collected many gold coins. He did not want anybodyto know about them. One day, his wife asked, "How many gold coins do wehave?"After pausing a moment, he replied, "Well! If I divide the coins intotwo unequal numbers, then 37 times the difference between the twonumbers equals the difference between the squares of the two numbers."The wife looked puzzled. Can you help the merchant's wife by findingout how many gold coins? 37(x-y) =x^2-y^2. You no that x^2-y^2=(x-y)(x+y).So (x-y) cancels on both sides to give x+y=37.so sum of unequal halves=37 which is the req answer. When I add 4 times my age 4 years from now to 5 times my age 5 years from now, I get 10 times my current age. How old will I be 3 years from now?
