Question 2.

Pratibha uses the digits '4', '7', '3' and '2', and makes the smallest and largest 4-digit numbers with them: 2347 and 7432. The difference between these two numbers is 74322347 5085. The sum of these two numbers is 9779. Choose 4-digits to make: Class 6

(a) the difference between the largest and smallest numbers greater than 5085.

(b) the difference between the largest and smallest numbers less than 5085.

(c) the sum of the largest and smallest numbers geater than 9779.

(d) the sum of the largest and smallest numbers less than 9779.

Solution:

(a) For it, we take the digits 4, 8, 3 and 2. Then, 84322348 6084, which is greater than 5085.

(b) For it, we take the digits 4, 6, 3 and 2. Then, 6432 2346 4086, which is less than 5085.

(c) For this, we take the digits 6, 7, 3 and 2. Then, 7632 2367 9999, which is greater than 9779.

(d) For this, we take the digits 6, 7, 3 and 1. Then, 7631 1367 8998, which is less than 9779.
