It takes 10 days for digging a trench of 100 m long, 50 m broad and 10 m deep. What length of trench, 25 m broad and 15 m deep can be dug in 30 days ? a) 400 m b) 200 m c) 100 m d) 89m Expl : More days, more length (Direct) Less breadth, more length (Indirect) More depth, less length (Indirect Days 10 : 30; Breadth 25 : 50; : : 100 : x Depth 15 : 10; :. 10 * 25* 15 * x = 30 *50 * 10 *100 x= (30*50*10*100)/10*25*15 = 400 So the required length = 400m
