A ship $55$ kms, from the shore springs a leak which admits $2$ tonnes of water in $6$ min; $80$ tonnes would suffer to sink her, but the pumps can throw out $12$ tonnes an hour. Find the average rate of sailing that she may just reach the shore as she begins to sink.

  1. $5.5$ km/h
  2. $6.5$ km/h
  3. $7.5$ km/h
  4. $8.5$ km/h

If $x=1+2a+3a^{2}+4a^{2}+\dots(-1 < a < 1)$ and $y=1+3b+6b^{2}+10b^{3}+\dots(-1 < b < 1),$ then find $1+ab+(ab)^{2}+(ab)^{3}+\dots$ in terms of $x$ and $y$. $\frac{x^{1/2} y^{1/3}}{x^{1/2}+y^{1/3}-1}$ $\frac{xy}{x+y-1}$ $\frac{x^{1/3}y^{2/3}}{x^{1/3}+y^{1/2}-1}$ None of these.
