Question

What is the biggest two-digit number you can make using the digits 2 and 7 without repeating any digit?

Answer 1

Say: Let’s find out the two-digit numbers that can be made using the digits 2 and 7 without repeating any digit.

Steps:
\(\bullet\) There are only 2 possible two-digit numbers that can be formed using the digits 2 and 7.
\(\bullet\) They are 27 and 72.
\(\bullet\) The biggest of the two is 72.
\(\bullet\) The abacus given in Option B has 7 beads over “T” representing 7 Tens and 2 beads over “O” representing 2 Ones.
\(\bullet\) 7 Tens and 2 Ones = 72.
\(\bullet\)Hence, Option B is the correct answer.
