The six-digit number 63X904 is an even multiple of 27. What does the digit X represent?
olga2289 [7]
Let's solve this problem step-by-step.

STEP-BY-STEP SOLUTION:

To begin with, let's establish that ( x ) can equal to any number from 0 to 9.

Meaning, that ( x ) is equal to one of the following: 0, 1, 2, 3, 4, 5, 6, 7, 8 or 9.

Now that we know which values ( x ) can equal to, we will simply substitute each of the numbers as potential values of ( x ) into the six-digit number and divide it by 27 to see if it is a multiple of 27.

If X = 0

= 63X904 / 27

= 630904 / 27

= Not a whole number

Therefore, X is not equal to 0.

If X = 1

= 63X904 / 27

= 631904 / 27

= Not a whole number

Therefore, X is not equal to 1.

If X = 2

= 63X904 / 27

= 632904 / 27

= Not a whole number

Therefore, X is not equal to 2.

If X = 3

= 63X904 / 27

= 633904 / 27

= Not a whole number

Therefore, X is not equal to 3.

If X = 4

= 63X904 / 27

= 634904 / 27

= Not a whole number

Therefore, X is not equal to 4.

If X = 5

= 63X904 / 27

= 635904 / 27

= 23552

ANSWER:

Therefore, the answer is:

X = 23, 552

A broker takes 2% as commission for the sale of property of value up to rupees 3,00,000. If the sale price is more than this, th
astra-53 [7]

Answer:

The broker's commission was rupees 8,250

Step-by-step explanation:

Selling price of property = rupees 450,000

The sale price is higher than rupees 300,000

Commission for rupees 300,000 = 2% × rupees 300,000 = rupees 6,000

Remaining amount = rupees 450,000 - rupees 300,000 = rupees 150,000

Commission for the remaining amount = 1.5% × rupees 150,000 = 0.015 × rupees 150,000 = rupees 2,250

Total commission = rupees 6,000 + rupees 2,250 = rupees 8,250
