Sol: Let the required number of hours be x. less men more hours(Indirect proportion). 15:36::25:x (15*x)=(36*25) x=(36*25) /15 x=60 For 15 men it takes 60 hours.3)If 9 engines consume 24metric tonnes of coal, when each is working 8 hours a day, how much coal will be required for 8 engines, each running 13 hours a day, it being given that 3 engines of former type consume as much as 4 engines of latter type?Sol: Let 3 engines of former type consume 1 unit in 1 hour. 4 engines of latter type consume 1 unit in 1 hour. 1 engine of former type consumes 1/3 unit in 1 hour. 1 engine of latter type consumes 录 unit in 1 hour. Let required consumption of coal be x units. Less engines, less coal consumed.(direct) More working hours, more coal consumed(direct) Less rate of consumption, less coal consumed (direct) 9:8 8:13 :: 24:x 1/3:1/4 (9*8*(1/3)*x)=(8*13*(1/4)*24) 24x=624 x=26 metric tonnes.<font size="3"><a href="chainrule1.html" target="right"><strong>BACK</strong></a></font></PRE></font></TD></TR></table></HTML>⌨️ 快捷键说明
