Congrats C Nagar! Well done and all the best with your apps!

8c3*3! = 336 336 - 330 = 6

11c4*4! : 11c3*3! = 8 : 1

it should be 90/3! = 15 we have to remove the repititions in the groups - (ab),(cd),(de) and (ab)(de)(cd) are the same group

1. 11c4*41 : 11c3*3! 2. 4/7

think it should be C st1. only gives us the median not the mean - not suff st2. only gives us the range - not suff together we know that the range is 100 and the median in 90, hence the range is 40 to 140 - suff

Congrats Riju!! Great Score!!

thnx guys..OA is C

should be B the number of women will increase if one of the men gets injured and is replaced by a women in the reserve. We know the number of wemen in the reserve but we need to know 'x' or the probability of one man getting injured. st1. does'nt give the number of men - not suff st2. gives us the ratio of men to wemen - x:y = 1:3, hence the probabilty of a man getting injured is 1/4 - suff
