>> Guest: WTF! How in gods name is that possible in two hours the MINUTE hand will pass through 720 degress. If it started at 12 and passed the entire hour it would return at 12. A cirlce containing 360 degrees it would do this twice 2 x 360 would be 720 degrees. Please explain to me how it would only traverse 45 degrees I really dont see how that is correct. In two hours, the minute hand of the clock rotates 
>> Guest: i think the answer to this question is wrong. you wrote 47 is the answer. 4+7=11 and is NOT 4 times as large as the sum (44?). the answer should be 36 In a twodigit number, the unit's digit is 3 great

>> micxj: let: x=father's age at present y= son's age at present two times the father's age is '8 more than 6 times his son's age' would be represented by this equation: 2x=8+6y 'Ten years ago, the sum of their ages was 44': (x10)+(y10)= 44 x+y20=44 x+y=44+20 x+y=64 yung age ng son ang tinatanong so, we need to find the value of x in order to get the value of y (son's age) if, 2x=8+6y then, x=4+3y since x+y=64 and x=4+3y: x+y=64 (4+3y)+y=64 4y+4=64 4y=644 4y=60 y=60/4 y=15 so the son's age is 15 Two times the father's age is 8 more than six time

>> micxj: i was confident that the correct answer must be 36. uhm,. here's my solution, please tell me if there's an error here: let the ten's digit be 'x' and the unit's digit be 'y' the number would be (10x+y) 'the unit's digit is 3 greater than the ten's digit' y=x+3 'the number is 4 times as large as the sum of its digits' 10x+y=4(x+y) if, y=x+3 and 10x+y=4(x+y) then, 10x+x+3=4(x+x+3) 11x+3=4(2x+3) 11x+3=8x+12 11x8x=123 3x=9 x=3 y=x+3 y=3+3 y=6 no.=xy x=3 y=6 no.=36 so the correct ans would be 36 right? In a twodigit number, the unit's digit is 3 great 
>> micxj: suppose that the population mentioned there was the population in the year 2007. on 2008(the 1st year), the population would be 105% of the population during 2007 on 2009(2nd yr), it'll be 110.25%(1.1025) because 1.05+(1.05x.05)=1.1025 on the 3rd year: 1.1025+(1.1025x.05)=1.157625 the asked value is the percentage it will increase after three years. after three year, the population would be 115.7625% or 1.1576% of the original population 115.76%100%=15.76% The population of the country increases 5% each ye 
>> micxj: correction:(i omitted the % sign after 1.1576) the asked value is the percentage it will increase after three years. after three year, the population would be 115.7625% or 1.1576 of the original population 115.76%100%=15.76% The population of the country increases 5% each ye

>> Guest: bez, it's jacky. let x be the rate of Oscar. y be the rate of james. if they are to meet after 32 seconds of running in opposite direction, that mins that the sum of the distances they've covered is equal to the circumference of the track. try to imagine it.. so, the working equation would be 32x + 32y =440. rate=distance/time. thus, the r of Oscar is 440/60. that is 22/3. so, we now have, 32(22/3) + 32y = 440 we multiply the equation ol thruout by 3 for simplification. so, we now have, 704+96y=1320 y=6.4166.. seconds that is the r of James. but wat is asked hir is the time it will take james to go around the track. so,the formula is t=d/r ryt? t=440/6.4166.. that's around 68. 57 seconds.. got it? :) It takes Oscar 60 seconds to run around a 440yard

>> Guest: Here is my solution. Kindly verify. x = amount of time needed by Peter to finish a job y = amount of time needed by Paul to finish a job 3 = amount of time needed by Peter and Paul working together to finish a job. this means that in an hour, 1/x = amount of work finished by Peter also, 8/x = amount of work finished by peter in 8 hours and in an hour, 1/y = amount of work finished by Paul and in an hour, 1/3 = amount of work finished by Peter and Paul working together "Peter and Paul can do a certain job in 3 hours." (1/x)+(1/y) = 1/3 "They worked together for 1 hour" means (1/x)+(1/y) "they worked together for 1 hour then Paul left and Peter finishes the rest of the work in 8 more hours."

>> dhax12: Mr. Rice can finish the wash in 15 min, his son paul takes twice as long doing the same wash that is 15 x 2 = 30min. one hint here is take the rate of each in one job and add their individual rate. Let x be the time to finish the wash. For mr. Rice his rate is 1/15, 1 indicates that that he can do 15 min to finish a "single" wash w/c is 1. For paul it is 1/30, the equation shall be, (1/15)x+(1/30)x=1 why equals to 1? It is said that they can finish washing (single job) if they work together. Solve for x, that will give you, x=10 min.
