| Hi,,,The ans for 1). Fifty minutes ago if it was four times as many minutes past three o,clock,how many minutes is it to six o,clock?sol:The trick to this is understanding the questn properly... the question often misleads most ppl...Thanks to shakuntala devi(puzzles 2 puzzle u page 1)U shud understand that 50 mins ago it was 4 times the mins (reuired to be 6 o'clock) past 3 o'clock.let x be the mins to 6 oclock.Now we know mins betn 3 to 6 are 180.These 180 would comprise of x+50+4x (as it was 4 times mins required to b 6)thrfore.. x+50+4x=180i.e 5x = 180-50=130x=130/5 = 26 mins |
