ABCD IS trapezium AB||CD AB=7,CD=5, AC and BD intersect at P. Area ABCD= 200, area triangle APB= 98. then sum of areas of triangles APD and BPC is? Explain?
How many positive three-digit integers ab c can represent a valid date in 2013, where either a corresponds to a month and b c corresponds to the day in that month, or ab corresponds to a month and c corresponds to the day? For example, 202 is a valid representation for February 2nd, and 121 could represent either January 21st or December 1st.

The interior of a square contains 30 points. This square, along with its interior, is partitioned into non-overlapping triangles, so that the vertices of the triangles consist of these 30 interior points together with the 4 corners of the square. If no 3 of these 34 points are collinear, then how many triangles do we obtain?

Calculate the weight and the % of zinc in the zinc copper alloy being given that the latter's alloy with 3kg of pure zinc contains 90% of zinc and with 2kg of 90% zinc alloy contains 84% of zinc.
1.Two solutions, the first of which contains 0.8 kg and the second 0.6 kg of salt, were poured together and 10kg of a new salt solution were obtained.Find the weight of the first and of the second solution in the mixture if the first solution is known to contain 10% more of salt than the second.
2. Two alloys of iron have different %age of iron in them.The first one weighs 6kg and the second one weighs 12kg. One piece each of equal weight was cut off from both the alloys and the first piece was alloyed with the second alloy and the second apiece alloyed with first one.As a result the %age of iron became same in the resulting two new alloys. what was the weight of each cut off piece??
3.Two cubes of bronze have their total weight equivalent to 60kg.The first piece contains 10kg of pure zinc and the second piece contains 8kg of pure zinc. what is the %age of zinc in the first piece of bronze if the second piece contains 15% more zinc than the first??

Two 12 hour clocks:P &Q; are set to show the correct time at 2'O clock in the afternoon. P gains time and Q loses time such that P gains 2 minutes for every 1 minute lost by Q. After some time before midnight on the same day if P and Q show 11'o clock and 8'o clock respectively, then what will be the time shown by P when both clocks show the same time again for the first time?
Plz explain, unable to solve clock problems like these.
