1.  In how many ways can 4 rings be worn in the index, ring finger and middle finger if there is no restriction of the number of rings to be worn on any finger? 

Ans 3*3*3*3

2. In how many ways can 3 different rings be work in 4 fingers given that one is allowed to wear more than one ring in finger? 

7c3*3!

Why two different methods are used?

@jaygandhi whatever method you go, the order of rings in fingers is important. 6C3 is for identical rings btw. The question seems to be taking distinct ones.

A natural number N when divided by a certain divisor leaves a remainder of 19. If twice the number is divided by the same divisor, then the remainder is 7. Which of the following is true? a) N lies between 10 and 20. b) N can only be 50. c) The divisor is 31. Your answer is correct d) Both (B) and (C).

Let's do this !

N = AD + 19 , 2N = BD + 7 , thus , (2A-B)D = 31 , which means D = 31. Only C
