Answer 1

Answer: (A) 448

Step-by-step explanation:

i hope you'r familiar with these kinda ques. so skipping some steps..

(since 1-99= 189 digits & 100-999= 2700 digits)

12345......(2425digits)

→189digits+3x digits = 2425digits

→3x digits = 2425 – 189 = 2236digits

→ x digits = 2236/3 = 745⅓ numbers

Now.. add numbers,

99+743= 844 and...dont forget about ⅓ number, its actually 1 digit out of number of 3 digit. so where we were,

=8448

and now ques. only ask bout last 3 digits, ans. is 448.

Answer 2

Answer:

189+3x=2425

x=2236/3

=745⅓

Then the number will be = 99+745=844

and the first number of that three number(because ⅓) is the last digit.

Then the digits will be 448
