If log 27 = 1.431, then the value of log 9 is:

If log 27 = 1.431, then the value of log 9 is:

A. 0.934 B. 0.945
C. 0.954 D. 0.958














Answer: Option C

 Explanation:

 log 27 = 1.431

  log (33 ) = 1.431

  3 log 3 = 1.431

  log 3 = 0.477

  log 9 = log(32 ) = 2 log 3 = (2 x 0.477) = 0.954.

 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
