Problem: টাকায় ১০ টা আম কিনে ১২ টা দরে বিক্রি করলে শতকরা কত ক্ষতি হবে?

View all: BANGLADESH BANK BANKERS | WRITTEN QUESTION (MATH) SOLVE | 1986

Correct Answer: উত্তরঃ শতকরা ১৬$\frac{২}{৩}$  % ক্ষতি হয়।

Explanation:

১২ টি আমের বিক্রয় মূল্য =১ টাকা

১০ টি আমের বিক্রয় মূল্য =$\frac{১+১০}{১২}$ টাকা = $\frac{৫}{৬}$ টাকা

১ টাকায় ক্ষতি হয় =$১-\frac{৫}{৬}$=$\frac{১}{৬}$টাকা

১০০ টাকায় ক্ষতি হয় =$\frac{১\times ১০০}{৬}$টাকা

১৬ $\frac{২}{৩}$ % ক্ষতি হয়।
