View all: BANGLADESH BANK BANKERS(AD) | WRITTEN QUESTION (MATH) SOLVE | 1990

Correct Answer: উত্তরঃ সঞ্চয়ের হার ২৫% ।

Explanation:

মনেকরি, মাসে আয় করেন x টাকা

৩ মাসের আয় =৩x টাকা

8মাসের আয় – ৪x টাকা

এখানে ৪ মাসের ব্যয় হবে = ৩x টাকা

অতএব, তিনি সঞ্চয়ের করেন =8x – ৩x= x

৪x টাকায় সঞ্চয় হয় x টাকা

১০০ টাকায় সঞ্চয় হয় টাকা=২৫ টাকা
