Greater than 15 less then 40
if you double me (15x2=30) The end becomes a zero
I believe its 30 but not positive. 1/5 of 30 is 6.

Look at the 1/5 part keep in mind the number that multiplies is less that 40 not the number you get AFTER multiplying. So lets go back to the 1/5 part , If 1/5 of it is 5 multiply 5 by 5 which equals 25 now x 2 and you have 50 which ends in 0 and your original number (25) is less 40 and greater than 15. BOOM
