If 96 is divided into four parts proportional to 5, 7, 4, 8 then the smallest part is :

 If 96 is divided into  four parts proportional to  5, 7, 4, 8 then the smallest part is :

 a) 16        b)14     c)20     d) 18




























Expl : Given ratio = 5 : 7  : 4  :  8 , sum of ratio = 24

     :. The smallest part = (96 *4/24) = 16

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 ?

 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
