Question

The manager of the museum has to solve the following incomplete division statement using the digits 8 and 9 only.


The missing digits A and B

• A. A = 9 and B = 8
• B. A = 9 and B = 7
• C. A = 7 and B = 8
• D. A = 8 and B = 9

Answer 1

The correct option is A A = 9 and B = 8

You know, $7\times 14=98$.

So, considering 7 and 14 as factor pairs, you will get 98.

Verify the equation $9800÷70=140$.

Using the standard algorithn for the division,

As calculated, the final quotient of $9800÷70$ is $140$.

So, rewrite the division statement as $9800÷70=140$.

Comparing this to $AB00÷70=140$, you get the following as the missing digits:
$A=9$ and $B=8$.

Hence, the division statement can be completed as:
