A batsman makes a score fo 58 runs in the 15th innings and thus increases his average by 3 runs. What is the average after 15th inning

• ANS: 16
  let the avg till 14th innings = x
  total runs after 14 innings = 14x
  total runs after 15 innings = 14x+58
  but given avg increases by 3 runs. so, total runs after 15 innings = 15*[3+x]
  Hence, 14x+58=15*[3+x]
  x=13
  so, avg after 15th innings=16

• ->runs /14=avg
  ->(runs +58)/15 =avg+3
  substitute runs =14*avg
  ->14a+58=15a+45
  ->a=13
  avg after 15th inn is 16.
