How many number of 2's would be used to type numbers from 112 to 375
Read Solution (Total 9)
-
- number of 2's from 112 to 199 = 19
number of 2's from 200 to 299 = 20+100 = 120
number of 2's from 300 to 375 = 18
So the result is = 157 - 9 years agoHelpfull: Yes(7) No(0)
- correction : ok its from 112 .... hence add another 2, answer is 157
- 9 years agoHelpfull: Yes(3) No(0)
- here it is said between 112 to 375 ; hence excluding 112,
we have 11 2's from 120 to 129 ( counting 10th place, and unit's place)
between 130 and 199 we have 7 2's at unit's place.
from 200 to 299 ----> we have 100 2's in hundredth place.
we have 10 2's in tenth place.
we have 10 2's in unit's place.
between 300 to 375
we have 10 2's in tenth place
we have 8 2's in unit's place.
total 2's = (11+7)+(100+10+10)+(10+8) = 18+120+18= 156 .
Simply breakdown the range into hundreds and ull be able to dissect it fast - 9 years agoHelpfull: Yes(2) No(1)
- 156 is the ans
- 9 years agoHelpfull: Yes(0) No(2)
- 156 answer
- 9 years agoHelpfull: Yes(0) No(2)
- from 112 to 1999 no 2=19
from 200 to 299= 120
from 300 to 375 =18
total 157 - 9 years agoHelpfull: Yes(0) No(0)
- 120,121.122.123.124.125.126.127.128.129,132,142,152,162,172,182,192,200,201--299,302,312,322 etc

- ans:156
from 112-130:1 2
120=129:11 2's because there is 2 in 10th place and at 122 we will get 2 in unit place
like we proced untill 375 so
the answer is 156 - 8 years agoHelpfull: Yes(0) No(0)
- Numbers of 2's from 200 to 299 = 119
Numbers of 2's from 112 to 199 = 19
Numbers of 2's from 300 to 375 = 18
So the result is (19+18+119)= 156. - 8 years agoHelpfull: Yes(0) No(0)
