Dhiman was admiring the output of her new program to generate random number. She had printed out the first 10 numbers of the results. She soon noticed something interesting. each of the 10 numbers had exactly one digit, in proper placement, of the 5 digit code she used to open her car door without key.
In the first number 14073, for example, Dhiman's car code could not be 34170 (2 digits correctly placed) or 92365 (none).
Find Dhiman's car entry code from these first 10 randomly generated number: 14073, 79588, 05892, 84771, 63136, 42936, 37145, 50811, 98174 and 29402.
if a number is divisible by 2 and 3 also.. Then it is also divisible by 2*3 = 6... Does this mean that if a number is divisible by 4 and also by 6.. then the number is divisible by 4*6 =24.... eg.. 36 and 12 are both divisible by 4 and 6 but not by 24... Why does the rule only apply to 4 and 6..
1) CONCEPTUAL DOUBT
2) PLZ ANSWER Skip

its not conceptual doubt . .we are taking LCM of 2 and not . not multiplication . . same for 4 and 6 . . if no. is devided by 4 and 6 , then also can be devided by their LCM i.e. 12 .
try this..
cn anyone help me with an easy approach??

There are 100 jars kept in an order , all containing an equal even number of pebbles . From the first jar, half the pebbles are taken and mixed with those in the second jar . Then again half the pebbles in the 2nd jar are taken and mixed with those in 3rd jar. This process goes on till half the number those in 99th jar are mixed with those in the 100th jar. In the entire process only the 100th and the 99th finally contained an odd number of pebbles . Find the minimum number of pebbles present initially in each jar ?
