The product of three positive integers is 6 times their sum. One of these integers is the sum of the other two integers. If the product of these three numbers is denoted by P, then find the sum of all distinct possible values of P.
P is the product of first 30 multiples of 30. N is the total number of factors of P. In how many ways N can be written as the product of two natural numbers such that the HCF of these two natural numbers is 19?
Cataholic told Alcoholic his score on the CAT, which was over 80. From this, Alcoholic was able to determine the number of problems Cataholic solved correctly. If Cataholic's score had been any lower, but still over 80 , Alcoholic could not have determined this. What was Cataholic's score? (Recall that the CAT consists of 30 multiple choice problems and that one's score, S , is computed by the formula , S=30+4C-w, where C is the number of correct answers and W is the number of wrong answers. (Students are not penalized for problems left unanswered.)

On a certain morning, Amar, Badri and Kedar start from a place P towards another place Q at 7:00 a.m., 7:25 a.m. and 7:50 a.m. respectively. They simultaneously reach a place M, which is twice as far from Q as it is from P, and continue their journey to Q. The fastest of them reaches Q at a time T and immediately turns back towards P, without changing his speed, and at the same time, the slowest of them increases his speed by a certain amount. Finally, all the three reach a place S (between M and Q) exactly 20 minutes after T. All three of them travel at constant speeds unless otherwise mentioned.

If the speed of Kedar when he started from P was 12 km/hr, what was the speed of Amar when he reached S?
12 km/hr
15 km/hr
18 km/hr
Cannot be determined
