Correct Answer: ক,খ ও গ যথাত্রমে ২০, ১১ ও ২৫ টাকা লাভ পায় ।

Explanation:

মনেকার, খ এর ঢাকা = x

ক এর টাকা = x + ৪৫

এবং গ এর টাকা = x + ৭০

প্রশ্নমমতে, x +x+৪৫ + x + ৭০= ২৮০

x =৫৫

ক এর টাকা = ৫৫ + ৪৫ = ১০০ টাকা

খ এর টাকা= ৫৫ টাকা

এবং গ এর টাকা = ৫৫ + ৭০ = ১২৫ টাকাক : খ : গ = ১০০ : ৫৫ : ১২৫ = ২০ : ১১ : ২৫

অনুপাত এর সমষ্টি = (২০ + ১১ + ২৫)= ৫৬

সুতরাং ক এর লাভ = ৫৬ এর $\frac{২০}{৬৫}$=২০ টাকাখ এর লাভ = ৫৬ এর $\frac{১১}{৫৬}$

= ১১ টাকা

এবং গ এর লাভ = ৫৬ এর $\frac{২৫}{৫৬}$

= ২৫ টাকা
