Answer 1

Answer:

3729

Step-by-step explanation:

XYZA be the four digit number

• The ones digit is the largest single-digit number is 9

therefore , A = 9

• thousands digit is 6 less than the ones digit.

therefore , X = A -6

X = 9 - 6 = 3

• The hundreds digit is 4 more than the thousands digit.

therefore , Y = 4 + X

Y = 4 + 3 = 7

• The tens digit is 5 less than the hundreds digit.

therefore , Z = Y -5

Z = 7 - 5 = 2

THEREFORE ,

1. X = 3
2. Y = 7
3. Z = 2
4. A = 9

The number is 3729
