Answer 1

Answer:

Hello Mate !!

Step-by-step explanation:

5 .For the greatest number, we will arrange these numbers in decreasing order and for the smallest number, we will arrange in increasing order.

∴Greatest number=76432 and Smallest number=23467

Hence, difference between greatest number and smallest number=76432−23467=52965

Therefore, the difference between the greatest and the least 5-digit number that can be written using the digits 6,2,7,4,3

is 52965.

6.Janary has 31 days

So, total production of screws in january is

2,825\times31\ =\ 87,575\2,825×31 = 87,575

Therefore,

The machine will produce 87,575 screws in the month of january.

7.Cost of one radio set = Rs. 1200

Therefore, cost of 40 radio sets = Rs. 1200 × 40 = Rs. 48,000

Total amount with the merchant = Rs. 78,592

Amount spent to purchase 40 radios = Rs. 48,000

Remaining amount after purchase = Total amount - Amount spent

= Rs. (78,592 – 48,000)

= Rs. 30,592
