If log 0.318=0.3364 and log 0.317=0.33320 then log 0.319 =?

a) 0.33365
b) 0.3368
c) 0.3396
d) 0.3369

• i will explain the logic
  log 0.318 / log 0.317 = log (0.318 - 0.317) = log 0.001 = 0.3364 / 0.33320 = 1.0096
  now,
  log 0.318 * log 0.001 = log (0.318 + 0.001) = log 0.319 = 0.3364 * 1.0096 = 0.3396
  so option c

• log 0.319=log0.318+(log0.318-log0.317) = 0.3396
  
• 9 years agoHelpfull: Yes(13) No(4)
• log 0.318/log0.317=log0.319/0.318
  
  so ans is 0.3396

• c)0.3396
  for log0.001 increase value increase is 0.0032 so the answer is (0.3332+0.0032) 0.3396.

• log 0.319=log0.318+(log0.318-log0.317) {(log0.318-log0.317)...here diference btwn 0.318 and 0.317 is equals to 0.319 and 0.318}
  ans; 0.3396

• log 0.317=0.3332 & log 0.318=0.3364
  now,
  last two digits of 0.3332 is 32 & last two digit of 0.3364 is 64 so if we multiply 32 by 2 then we get 64
  so as well if we multiply 32 by 3 then we get 96
  so log 0.319 = 0.3396 (Ans)
  so option c is the right ans
