Avg of 11 innings, x= a/11, => a = total runs in 11 innings 11x=a, , , ,

Avg. after12 innings, acc to question, x+2 = total runs scored in 12 inngs/ 12

Total runs scored in 12 inngs= total scored in 11 inngs+63 => a + 63=>> 11x + 63, ,


Avg . after 12 inngs from above equations,
x+2 = (11x +63)/12
=>12x+24= 11x + 63

=>12x-11x= 63 - 24
=> [ x = 39], ,,,
So avg of 12 inngs, increases by 2 runs so, x+2 =>39 + 2 =41, ,,,final answer
