Step-by-step explanation:

2) amount on earns per day = Rs. 270

therefore, amount he will in a week = Rs. 270 x 7 = 1890

therefore, amount he will in 4 weeks = Rs. 1890 x 4 = Rs 7560

3)start with thousand place

No of ways to fill the place -4 (as 4 number are available)

Now lets fill hundreds place

No of ways to fill the place-3 (as 1 number is used to fill thousand place)

Now lets fill tens place

No of ways to fill the place -2 ( as 2 numbers are ysed to fill the thousands and hundreds place respectively )

1 number is left which is used to fill ones place

No of 4 digit numerals possible with 4,2,6,9 = No of ways to fill thousand place × no of ways to fill hundreds place × no of ways to fill tens place × no of ways to fill ones place

4x3x2x1 = 24

24 numbers can be made .

greatest number = 9642

smallest number = 2469
