LET'S COUNT

[gabriele]

still a new puzzle from Adolfo:

a goal number from 101 to 999 is given
with
5 number from 1 to 9 and one additional number among 25,50,75,100

using the 5+1 numbers and the 4 mathematical operations (+ - : x)
you must obtain the goal number

there are two ways to solve

the minimal : using the smaller number of passages ,
the maximal using all 5+1 numbers.

let's start with a un test:

goal: 993

numbers: 9,4,1,7,8,25

can you solve it using both methods?
how long to solve it?
