: Concept: 1 Mark
Solution: 1 Mark
Shweta has more money than Rahul. If we compare both the numbers, then
the number with the greater valued digit on the extreme left will be greater. If the digits on the extreme left of the numbers are equal, then the digits to the right of the extreme left digits are compared and so on.Therefore, Rs.1501 is greater than Rs.1001. Now,1501-1001 = 500
Shweta has Rs 500 more than Rahul.
