Correct Answer: TK 1259.72

Explanation:

৮% বার্ষিক চক্রবৃদ্ধি হারসুদে ১,০০০ টাকা ৩ বছরের জন্য ব্যাংকে জমা করে

এখানে বার্ষিক সুদের হার r = ৮%

বছর n=৩

আসল p= ১,০০০ টাকা

আমরা জানি,

চক্রবৃদ্ধি সুদের ক্ষেত্রে, সুদাসল = $P(1+r)^{n}$

= $১০০০(১+৮\%)^{৩}$

=$১০০০(\frac{১০৮}{১০০})^{৩}$

= ১২৫৯.৭১২ টাকা
