Ann replaces letters in the calculation KAN + GA - ROO with some of the numbers from 1 to 9 and then calculates the result. The same letters are replaced by the same numbers and different letters by different numbers. What is the largest possible result she can get?

The largest possible result she can get is 550

Step-by-step explanation:

Here we have that to find the largest possible result, the numbers from which the last number is subtracted from should be the largest possible, hence

Whereby, we had K × A × N + G × A - R × O × O, then;

K 9

A8

N7

G6

A8

R2

O1

O1

will give, 504 + 48 - 2 = 550

If however, the A = 7 and N = 8 we have;

504 + 42 - 2 = 544

Hence, the largest possible result she can get = 550.
