The seats in an Engineering college for Computer science, electronics and civil are in the ratio of 5 : 7 : 8. There is a proportion to increase these seats by 40%, 50% and 75% respectively. What will be the ratio of increased seats ?

The seats in an Engineering college for Computer science, electronics and civil are in the ratio of 5 : 7 :
     8. There is a proportion to increase these seats by 40%, 50% and 75% respectively. What will be the
     ratio of increased seats ?

    a) 2 : 3 : 4     b) 6 : 7 : 8        c) 6 : 8 :  9       d) none of these






















. Expl : Originally, let the number of seats for Computer science, electronics and civil
      are  5x : 7x : 8x respectively.

    Number of increased seats are (140% of 5x), (150% of 7x) and (175% of 8x)

   7x : 21x/2 : 14x = 14x : 21x : 28x = 2 : 3 : 4.

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
