mean = 58
no. of matches = 9
thus, total number of runs in 9 innings = 58*9 = 522 runs
let the score in tenth innings be x.
mean in 10 innings = (522+x)/10
61 = (522+x)/10
thus, x can be found by solving this equation.
61*10 = 522+x
610 = 522+x
thus, x=610 - 522 = 88 runs
so, the cricketer should score 88 runs in his tenth innings to raise his mean to 61.
