Correct Answer: উত্তরঃ ক, থ কে ২৫০০০ টাকা ধার দিয়েছিল ।

Explanation:

মনেকরি, ক, খ কে ধার দেয় = x টাকা

১ বছরের সুদ মূলধনের $\frac{১}{৮}$ অংশ =$\frac{x}{৮}$ টাকা

৫ বছরের সুদ মূলধনের=$\frac{৫x}{৮}$ টাকা

সুদাসল = x+$\frac{৫x}{৮}=\frac{৫x}{৮}$টাকা

গ এর নিকট সুদ পায়=$\frac{5\times১৩x}{১০০\times ৮}$

প্রশ্নমতে, $\frac{5\times১৩x}{১০০\times ৮}$

=>$x=\frac{2031.25\times 100\times 8}{5\times 13}$

x=২৫০০০
