let the nos be a and b. Let A,G,H be a.m ,g.m.,h.m.we know A,G,H are in G.P.so, G^2=AH (eqn1)given:G=H+12 (eqn2) A=G+13 so,G=A-13 (eqn3) eqn(2)*Eqn(3) G^2=AH-156-13H+12A eqn(4) compare (1) and (4)12A=13H+156 eqn(5)by(2)&(3)A= H+25 eqn(6)by(6)&(5)A=169&H=144We know, A=a+b/2 338=a+b eqn(7) by knowing the value of A&H we get the value of G 156but G^2=ab so, ab=24336 eqn(8)by (7)&(8) we get the nos as 234&104

you can solve it by applying basic eqns in kinematics.initially the bullet was at rest and it has aquired the velocity of 400m/s after travelling through barrel of 0.80m. just find the accn involved and you will get the force .u=0v=400m/ss=0.80ma=v^2-u^2/2s =1000m/s^2force=m*a =5N ans

according to me this is the best decision taken by any government.sibal needs to be appreciated. this will discourage cramming in coaching centres . just cramming the results of the articles and not having the fundamental knowledge would not help
