Would be 60, there is a theorem on internal intersection of secants...angle formed is half the sum of arcs/central angles?

according to the euler's theorem.. 5^36-1 mod 12^n is 0 when E(12^n) is a factor of 36.
E(12^2)=36 which the largest factor of 36. hence 2 is the answer.

(1+4)^36 - 1 = [36c0 * 1^36 *4^0 + 36c1*1^35 * 4^1 + 36c2*1^34*4^2+.... - 1]/12
[36*4 + ....]/12 ; 36*4 = 12*12 ; so highest power of 12 that can divide 5^36-1 is 2 .
[36*4 + ....]/12 ; 36*4 = 12*12 ; so highest power of 12 that can divide 5^36-1 is 2 .
Two points are chosen uniformly at random on the unit circle and joined to make a chord C1. This process is repeated 3 more times to get chords C2,C3,C4. The probability that no pair of chords intersect can be expressed as a/b where a and b are coprime positive integers. What is the value of a+b?

A dishonest milkman earned 25% profit by mixing water into it. What is the percentage of water in mixture he sold this milk solution at cost price??????

CP=100(for 100% pure milk)
100-x/x = 1/4
400=5x
x=80
hence 20% water?
20
assume 100l of milk initially and he adds 25 litre of water to gain 25% profit =>25/125 =20%
What is the percentage of water in mixture
