Answer 1

Answer:

1. the difference between the greatest number and smallest number formed using the digits 6, 2, 7, 4, 3 each digit occurring only once= 52695
2. Cost of one radio Set = Rs. 1200

Cost of 40 radio set = 1200 × 40= Rs. 48,000

Now, total money with merchant = Rs. 78,592

Money spent by her = Rs. 48,000

Money left with her= Rs. (78,592 – 48,000) = Rs.30,592

Therefore, Rs. 30,592 will remain with her after the purchase
