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?
Let x= current age 4(x+4) +5(x+5) =10x4x+16+5x+25=10x9x+41=10x10x-9x=41so x= 41 yearsNow the age is 41+3=44years
A tennis championship is played on a knock-out basis, i.e., a player is out of the tournament when he loses a match.(a) How many players participate in the tournament if 15 matches are totally played?(b) How many matches are played in the tournament if 50 players totally participate?
a] See you don't need to sum it up. since it's a knock out only 1 person emerges winner finally.So 15+1=16 Because after 15 matches finally we should have 15losers and 1winner.b]49.its always
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.
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
