Batting average for 7 innings = 35
So, the total runs scored in 7 innings = 7 * 35 = 245
He scored 27 runs in the 8th innings
Total runs scored in 8 innings = 245 + 27 = 272
Average score for 8 innings = 272/8 = 34
If he wants to increase his average to 36 in 8 innings....
Total runs scored = 8 x 36 = 288
Total runs scored in 7 innings = 7 x 35 = 245
No. of runs needs to be scored in 8th innings to get average 36 is = 288 - 245 = 43
