A person forgot his 5 digit pin code but remembers some hints:

1st digit is square of second digit

Sum of 2nd & 3rd digits makes 10

4th digit is 2nd digit +1

Sum of 5th and 3rd digit makes 14

Sum of all digits = 30

… can you decode the pin-code

A weird person.. remembers so many thinks about the pin but not the pin itself

@ Usman: … Yeah must be a Mensan graduated from FAST-NU Lahore

square of 3 +3+7+(3+1)+7 = 30

93747

By considering vwxyz as 5 digit and applying rules we will get 93747

9 3 7 4 7

93747

93747

it is 93747

93747. Simple algebra.

1st digit is square of second digit

3*3=9

3

7 ,3+7=10

3+1= 4

7 7+7=14

30 9+3+7+4+7=30

93747……….how can any person remember so weird hint instead of simple pin code :p

93747

logical process:

digits =>……………………..1…2…3…4…5

1st sq of 2nd => ………….1…1…?…?…?

(anymore will result ……..4…2…?…?…?

in two digit numbers) ……9…3…?…?…?

2nd + 3rd=10=> ………….1…1…9…?…?

………………………………….4…2…8…?…?

………………………………….9…3…7…?…?

4th = 2nd + 1=> ………….1…1…9…2…?

………………………………….4…2…8…3…?

………………………………….9…3…7…4…?

5th + 3rd = 14 => ………..1…1…9…2…5

………………………………….4…2…8…3…6

………………………………….9…3…7…4…7

now we got 3 possible combinations:

……………………………… …1…1…9…2…5

………………………………….4…2…8…3…6

………………………………….9…3…7…4…7

Sum of all = 30……………1…1…9…2…5 = 18

………………………………….4…2…8…3…6 = 23

………………………………….9…3…7…4…7 = 30 (yeah!!!)

Therefor, last combination of numbers is the pin

That is, 9 3 7 4 7

Simple aye!!!

This question is more about starting with an initial estimate then involving Algebraic equations. The easiest way is to guess the highest square below 10 i.e. 9. Then proceed afterwards. The 2nd digit would be 3, 3rd digit would be 7, 4th digit would be 4, 5th digit would be 7. Then find out sum of all the digits which would be 9+3+7+4+7=30. Hence, the Pin code would be 93747.

93747. Pretty simple though..

1: pehla digit 2nd digit da square hey

2: 2nd plus 3rd digit =10

3: 4th digit= 2nd digit + 1

4: 5th digit + 3rd digit=14

5: sub digits ko plus krain =50

what is pincode

ans plz

1. Square of Secon digit = 1 or 4 or 9 (Since each number of pin is 0-9 Main Digit has to be 0-3 and since 0^2 = 0 Thus ignore hence 1-3)

2. Main Digit = 1 or 2 or 3

3. Sum of Main digit and this = 10 (either 9 or 8 or 7 )

4. Main digit +1 = 2 or 3 or 4

5. This and 3rd digit = 14 so (either 5 or 6 or 7)

sum of all digits = 30 so,

1+1+9+2+5 = 18

4+2+8+3+6 = 23

9+3+7+4+7 = 30

Hence Pin Code = 9 3 7 4 7

Thnks for ur time
