Answer:
180 times mistakenly 8 typed.
Step-by-step explanation:
600 - 799
In 600-699 hundred places instead of 6 the 8 typed = 100 times
at ten's place = 10 times
at one's place = 10 times
now, 8 also been typed right so in
=> at ten's place = 10 times
=> at one's place = 10 times
600-699 = 100+10+10+10+10 = 140
In 700-799 hundred place 8= 0 (8 not possible)
6 replaced by 8 => at ten's place = 10 times
at one's place = 10 times
8 typed => at ten's place = 10 times
at one's place = 10 times
here, 10+10+10+10= 40
Total => 140 + 40 = 180
