Question

The sum of all possible two-digit numbers formed from three different one-digit natural numbers when divided by the sum of the original three numbers is equal to

• A. $36$
• B. $22$
• C. $18$
• D. $24$

Answer 1

The correct option is B $22$

Let us take the three different one-digit numbers
as 5, 6 and 7
The two-digit numbers formed from these
numbers are 56, 65, 67, 76, 57 and 75
$\therefore$ Required quotient = $\frac{56+65+67+76+57+75}{5+6+7}=\frac{396}{18}=22$
