Euler bas jaan lo! simple h!!
Let X/Y ka remainder nikalna ho (X and Y need to be co-primes)
First find euler number of Y.
suppose Y=10
10=2*5 so iska euler no hoga 10(1-1/2)(1-1/5) = 10*1/2*4/5= 4
so agar 7^(4000000)/10 nikalna ho toh remainder 1 hoga kyunki numerator ki power denominator ki euler no ya uski multiple h.
Yani jab bhi numerator aur denominator aapas m co-prime ho aur numerator ki power denominator ki euler no ya uski multiple ho toh remainder 1 hoga !! Baki questions simple division rules se kar lena !! kaafi h..

@shawshanks Sir below is the snapshot of Quantum Cat. I am not able to get 2nd and 3rd terms in the ratio.
Shouldn't second term be 2x *6 + 6x * 6 as B invested 4x after 6 months and so his investment for last 6 months becomes 2x(old) + 4x(new) = 6x.
Monthly incomes of A and B are in the ratio 4:3 and their savings are in the ratio 3:2. If the expenditure of each is Rs 600 then monthly income of each is?
