Answer 1

Answer:

4829 is her pin number

Step-by-step explanation:

x + 2x + 10 - 2x + 2x + 1 = 23

3x + 11 = 23

3x = 23 - 11

3x = 12, x = 4

Therefore, Four digits are 4, 8, 2, 9

Answer 2

Answer:

Fourth digit is two minus of the total of second and third digit ....

total of second and third digit is 10

• so , forth digit = 10 -2 = 8

sum of all the digits = 22

then , first digit + second digit + third digit + forth digit = 22

first digit + 10 + 8 =22

first digit +18 = 22

• first digit = 22-18 = 4

first digit is the half of the second digit

first digit × 2 = second digit

4 × 2 = second digit

• second digit = 8

second + third digit = 10

8 + third digit = 10

• third digit = 10 - 8 = 2

so , the pin no. is 4828
