Arrange the 9 digits in three arithmetic sums. Using three of the four operations of addition, subtraction, multiplication, or division. Use no signs except the signs using those operations. Here is an example You must use digits 1 - 9 and only ONCE

3 + 4 = 7

9 - 8 = 1

30 / 6 = 5

The above example is not correct, because it does not contain 2, and three is repeated.

i. 5 + 4 = 9

ii. 2 x 3 = 6

iii. 8 - 7 = 1

Step-by-step explanation:

Given: The basic arithmetic operations: addition, subtraction, multiplication or division.

           Digits from 1 - 9

Using three arithmetic operations - addition, subtraction, multiplication, and the given digits, the following three expressions can be formed:

i. 5 + 4 = 9

ii. 2 x 3 = 6

iii. 8 - 7 = 1

It can be observed that there is no repetition of digits in the above expressions as required.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
