        1. 3rd to left of 7th from right means 4th from right

          so mine

          1. PC

            3rd to the left of 7th from right means-
            as left and right case opposite case so should be added means:7+3=10 from the right
            R+R=minus
            L+L=MINUS
            L+R=add
            R+L=add
            or we go from basic then also..jo 7th element hoga from the ryt end uska 3rd left.
