Question

.Using the digits 3,0,8,7,1 make the smallest 7-digit number (repetition of 1 digit is allowed)​

Answer 1

Answer:

The smallest positive 7 digit number if you have to use all 5 digits is 1002378.

Step-by-step explaination :

Actually answer would be 1000378. But in the question you mentioned only one digit allowed for repetition. So, removed zero from 10thousand's place. But we can't add 1 because already we took it in 10lakhs place. So, 2 is smallest number in that case.
