Question

Four friends play a number game. Each of them writes their favourite number. Who wrote the smallest number?

• A. Alka
• B. Mona
• C. Raj
• D. Rahul

Answer 1

The correct option is D Rahul

To identify the smallest number from a given set of numbers having equal number of digits, we need to compare the digit in the thousands place of each number.

$\begin{array}{cc}\text{Number}& \text{Number of thousands}\\ \underset{–}{6}572& 6\\ \underset{–}{7}297& 7\\ \underset{–}{5}425& 5\\ \underset{–}{1}252& 1\end{array}$

Since 7 > 6 > 5 > 1, the smallest number is the one with 1 in the thousands place which is 1252, written by Rahul.
