Aboy forgot his pin code which was 5-digit number, but luckily for him, he remembered some hints that could remind him of that password.
here are those hints:
1. first digit is equal to the square of second digit.
2. second digit plus third digit is equal to 10.
3. fourth digit equal to the second digit plus 1
4. fifth plus 3rd digit is 14
5. sum of all the five digits equals 30.
whats the pin code?

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

what's the question?

step-by-step explanation:

there is no question.
