Question

What is the smallest two-digit number that can be made using the digits 2 and 1 without repeating any digit?

Answer 1

Say: Let’s find out the two-digit numbers that can be made using the digits 2 and 1.

Steps:
\(\bullet\) There are only 2 possible two-digit numbers that can be formed using the digits 2 and 1 without repeating any digit.
\(\bullet\) They are 21 and 12.
\(\bullet\) The smallest of the two is 12.
\(\bullet\) The abacus given in Option C has 1 bead over “T” representing 1 Tens and 2 beads over “O” representing 2 Ones.
\(\bullet\) 1 Tens and 2 Ones = 12.
\(\bullet\)Hence, Option C is the correct answer.
