If 0.4 of a number is equal to 0.06 of another number, the ratio of the numbers is :

If 0.4 of a number is equal to 0.06 of another number, the ratio of the numbers is :

a) 2 :3      b) 3 :4    c)3:20           d) 20 : 3










Expl : 0.4A = 0.06B -> A/B = 0.06/0.40 = 6/40 = 3/20

     :. A : B = 3 : 20

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
