Question

The perfume store’s number has $7$ Tens, the statue store’s number has $1$ more face value than the perfume store in Ones, and the jewellery store has $1$ Hundred for the total stores on one side of the city. If the face value of the digits at Tens and Ones place is swapped, we will get the total number of structures that are on the other side of the city. Which of the following is that total number?

• A. $178$
• B. $711$
• C. $187$
• D. $117$

Answer 1

The correct option is C $187$

Detailed step-by-step solution:
Number of perfume stores $=7$ Tens, i.e., $70,$ the face value is $7.$
The statue store has 1 more face value than the perfume store in Ones; therefore, the number of statue stores $=7+1=8,$ i.e., $8$ Ones.
Number of jewelry stores $=1$ Hundred, i.e., $100.$
Therefore, total stores on one side of the city $=178$

Face value of the digit in the Tens place $=7$
Face value of the digit in the Ones place $=8$
After swapping $7$ and $8,$ we get $187.$




Hence, Option C is correct.
