Question

When Rashi ordered pizza and coke, the bill had the digits A and B not visible clearly.

$$\begin{array}{ccc}PizzaA& 1& 2\\ Coke+3& 1& B\\ 5& 2& 5\end{array}$$

Using the information visible on her bill, find the digits A and B respectively.

• A. A = 2, B = 1
• B. A = 3, B = 5
• C. A = 1, B = 3
• D. A = 2, B = 3

Answer 1

The correct option is D

A = 2, B = 3

In the tens place, the numbers being added are 1 and 1. The sum given in the tens place is 2, which means there is no carry over throughout the summation.

A + 3 = 5 i.e A = 5 - 3 = 2 and

2 + B = 5 i.e B = 5 - 2 = 3

$$\begin{array}{ccc}Pizza2& 1& 2\\ Coke+3& 1& 3\\ 5& 2& 5\end{array}$$
