Question

Alexandar wants to build a luxurious tree house. A tree house builder tells him that the cost of making the tree house is the largest five-digit number from the digits 3, 4, 2, 9, and 0 with repetition. Help Alexandar find the cost of building the tree house.

• A. 94,320 dollars
• B. 90,000 dollars
• C. 10,000 dollars
• D. 99,999 dollars

Answer 1

The correct option is D 99,999 dollars

The digits available are 3, 4, 2, 9, and 0.

Here, the largest digit = 9

Since repetition is allowed, the largest five-digit number is
99,999.

Hence, the cost of building the tree house = 99, 999 dollars
