• B. 1,03,679
• C. 9,76,310

Answer 1

The correct option is B 1,03,679

Arrange the digits in the increasing order of their values.
0 < 1 < 3 < 6 < 7 < 9
Place the smallest digit at the largest place and arrange the remaining digits in an increasing order.
Watch out! 13,679 has only five digits since 0 has no value at the beginning of a number!
To form the smallest six-digit number, place 0 in the second highest place.Thus, the smallest six-digit number that can be formed is 1,03,679.
