have a doubt in the proof of basic proportionality theorem..ABC be the triangle D and E are points on AB and AC..now in triangle ADE a perpendicular is drawn from E on to AD.let it be EN..now in triangle BDE they have taken area as 1/2*BD*EN(as EN IS THE HEIGHT FOR TRIANGLE ADE WHY HAVE THEY CONSIDERED IT TO BE THE HEIGHT FOR TRIANGLE BDE)😠😠
A punching machine is used to punch a circular hole of diameter two units from a square sheet of aluminium of width 2 units, as shown below. The hole is punched such that the circular hole touches one corner P of the square sheet and the diameter of the hole originating at P is in line with a diagonal ofthe square. "
Find the area of the part of the circle (round punch) falling outside the square sheet.

There are three cities: A, B and C. Each of these cities is connected with the other two cities by at least one direct road. If a traveller wants to go from one city (origin) to another city (destination), she can do so either by traversing a road connecting the two cities directly, or by traversing two roads, the first connecting the origin to the third city and the second connecting the third city to the destination. In all there are 33 routes from A to B (including those via C). Similarly, there are 23 routes from B to C (including those via A). How many roads are there from A to C directly?

The length of the circumference of a circle equals the perimeter of a triangle of equal sides, and also the perimeter of a square. The areas covered by the circle, triangle, and square are c, t and s, respectively. Then,
(1) s > t > c (2) c > t > s (3) c > s > t (4) s > c > t

Rectangular tiles each of size 70 cm by 30 cm must be laid horizontally on a rectangular floor of size 110 cm by 130 cm, such that the tiles do not overlap. A tile can be placed in any orientation so long as its edges are parallel to the edges of the floor. No tile should overshoot any edge of the floor. The maximum number of tiles that can be accommodated on the floor is ?

100 million bacteria can completely decompose a garbage dump in 15 days and 60 million bacteria can do so in 30 days. If same quantity of garbage is added to the initial quantity of the dup everyday, how many bacteria will be required to completely decompose the dump in 10 days?
Please specify the approach too
Can anyone please tell a better approach (Fraction method)
A is twice as effiicient as B. If they complete a work in 30 days, Find the time required by each of them to complete the work independently.
My Approach
A=2B
30A+30B = 100% work
i.e. 90B = 100% work
B = 1.11%
work done by B inone day = 1.11% (B take 90 days to complete)
Hence A will take 45 Days
