Answer:
According to the question 95 is the correct option.
Step-by-step explanation:
step 1:
Total number of 1's between 149- 159 is 12 [ because it starts from 149 not from 150 ]
Total number of 1's between 160- 169 is 11
so, following the above pattern Total number of 1's between 149- 199 is
[ 12+( 11* 4) ] = 56
step 2:
Total number of 1's between 200- 210 is 2
Total number of 1's between 211- 220 is 10
* Total number of 1's between 221- 230 is 1 * [ by following this pattern you have to calculate 231-240, 241-250........ 291-300 ]
so total number of 1's between 200- 300 = 2+ 10 +( 1 * 8 )= 20
step 3:
Total number of 1's between 301- 310 is 2
Total number of 1's between 311- 320 is 10
Total number of 1's between 321- 330 is 1 [ by following this pattern you have to calculate 331-340, 341-350........ 371-380 ]
Total number of 1's between 381- 381 is 1
so total number of 1's between 200- 300 = 2+ 10 +( 1 * 6 ) + 1 = 19
step 4:
total number of 1's between 149 - 389 = 56 +20 +19 = 95
