Question

If $a$, $b$, $c$, and $d$ are replaced by four different digits from $1$ to $9$, inclusive, then what's the largest possible value for $a.Bc + 0.D$ ?

Answer 1

Answer:

The largest value is 10.56

Step-by-step explanation:

We are given to find the largest value of

$Z=a.Bc+0.D$

so, 'a' must be largest value among them

and we have select from 1 to 9

so, a=9

since, B and D are at same places

so, we can have largest value

B=8

D=7

now, we can select next highest value

c=6

now, we can plug these values

$Z=9.86+0.7$

$Z=10.56$
