⇒ Number of days the food lasted for 80 boarders = \dfrac{40 \; * \; 90}{80}

80

40∗90

⇒ Number of days the food lasted for 80 boarders = 45

\begin{gathered}\\\end{gathered}

Number of the food will last = 45 - 40

⇒ Number of the food will last = 5

\begin{gathered}\\\end{gathered}

∴ The food will last for 5 more days.
