weight of the 1st tank when empty= 88kg
It is very easy to remember the ID number of my ATM card which is a nine digit number and every digit is distinct. If i tell you some clues then you will be able to find it.Consider my numer as PQRSTUVWX corresponing to 1 to 9 digits though not repository .The Id is divisible by 9. if you delete the digit at its units place, the remaining 8 digit number of my ID is divisible by 8. If you again delete the last digit of the 8 digit number the remaining 7 digit number is divisible by 7 and the process goes on.what is the number??
Two trains begin to enter a tunnel simultaneously at opposite ends on parallel tracks. While train A takes 10s to completely enter the tunnel, train B takes only 5s.

Two trains T1 and T2 are travelling on parallel tracks and in opposite directions. P1 and P2 are two persons who are travelling in T1 and T2 respectively. When the two trains just start to cross each other, P1, who is at the tail end of T1, starts running towards the front end of T1, at a speed of 6 m/s, and P2, who is at the front end of T2 starts running towards the tail end of T2 at a speed of 4 m/s. If the lengths of T1 and T2 are 216m and 432 m respectively, and the speeds of T1and T2 are 108km/hr and 144 km/hr respectively, in how much time (from the time T1 and T2 start to cross each other) will the two persons cross each other? A) 5 s B) 9 s C) 6 s D) none
