If a batsman scored 44 runs in his last match, then his average runs increased by 0.2 runs.If he scored 4 runs in his last match ,then his average runs is decreased by 0.6 runs ,then what is the total match played by the batsman

• 50
  
  Let matches played before last match=n and average=x.
  Then, (nx+44)/(n+1) = x+0.2 => 0.2n+x=43.8 ---(i) and
  (nx+4)/(n+1)=x-0.6 => -0.6n+x=4.6 ---(ii)
  Solving eqn. (i) & (ii), x=34, n=49
  Therefore, total matches played including last match=49+1=50
