Answer

Let the two digits be x & y


From given data in the question, we get


x + y = 3(x - y)


x + y = 3x - 3y


=> 2x = 4y


x/y = 2/1


For having the 2:1, numbers satisfying are


12, 21, 24, 42, 36, 63, 48, 84


From this 36 is eleminated because it is a perfect square and no others are prime or perfect squares.


Hence, there exists 7 such 2-digit numbers => 12, 21, 24, 42, 63, 48, 84.

Q:

What is my PIN number ?

15284979_1144906482283121_6846321683334684022_n1500009455.png image

A) 93714 B) 42789
C) 36671 D) 93747
 
Answer & Explanation Answer: D) 93747

Explanation:

From the hints,

Only two options for 1st and 2nd digits => 4,2 and 9,3 since it is single digits

Sum of second and third digit  = 10 

If 2 => 3rd digit = 8

If 3 => 3rd digit = 7

4th digit = 2nd digit + 1 => (2+1 =3) or (3+1 = 4)

Sum of all digits = 30

Let 5th digit be x

=> 1st possibility = 4 + 2 + 8 + 3 + x = 30 => x = 13 (Not possible since it has 2 digits)

=> 2nd possibility = 9 + 3 + 7 + 4 + x = 30 => x = 7

Therefore, the PIN is 93747

The distance is = Length of trains = 360 mts 

Speed = 58 - 50 = 8 kmph x 5/18 m/s
