• A. 9,74,310
• B. 0,97,431
• C. 0,13,479
• D. 1,03,479

Answer 1

The correct option is D 1,03,479

Arrange the digits in the increasing order of their values.
0 <1 < 3 < 4 < 7 < 9
Place the smallest digit at the largest place and arrange the remaining digits in an increasing order.Watch out! 13,479 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 1,03,479.
