Can anyone tell the approach?

A has 100 L milk, B has 200 L water. 40 L from A is poured into B, from this solution 40 L is put back into A. This process is repeated infinite no of times. Find the final conc of milk in A. Ans and aproach ?

In Triangle ABC, M is the mid point of BC and N is the mid point of AM. BN when extended intersects AC at D. If the area of triangle ABC is 20 sq units, find the area of triangle AND.

Please provide explanation also.

a. 1.67 sq units

b. 1.5 sq units

c. 2 sq units

d. 3 sq units

  The points (3, 3), (h, 0) and (0, k) are collinear if. ?

999999/22 please tell me easy trick to find remainder.

highest power of 2 which divides 3^1024-1 is?

oa:12

my approach (2+1)^1024-1= 1024C02^1024+....+1024C1023(2)(1)^1023+1-1

so highest power of 2 in second last term in 1024*2 which is 2^11.

Correct me where am I going wrong?

If |r - 6| = 11 & |2q - 12| = 8, what is the minimum possible value of q/r?

Plz explain approach!!

Hi guys,

Please help me on this one.I find P&C and probability difficult.

Find the number of integral points that satisfy the following equation

| x | + | 5 y |

Plz explain the answer

if doing by graphical method .. plz paste the image of the graph and points !!


Two functions F(x) and G(x) are defined as follows: F(x) = x^2 + 8x - 18, G(x) = 3x - 6 - x^2 If H(x) = Maximum (F(x), G(x)), for what value(s) of x would H(x) assume its minimum value?

plz explain!!
