Find the principle amount that produces a total value of Tk. 1014 at 4 years with 7.5 percent simple interest rate.

Find the principle amount that produces a total value of Tk. 1014 at 4 years with 7.5 percent simple interest rate. Correct Answer 780

৪ বছরের সুদাসল = ১০১৪ টাকা আসল ১০০ টাকা হলে, ১ বছরের সুদ = ৭.৫ টাকা ৪ বছরের সুদ = ৭.৫ × ৪ টাকা ৪ বছরের সুদাসল = ১০০ + ৩০ = ১৩০ টাকা সুদাসল ১৩০ টাকা হলে আসল = ১০০ টাকা সুদাসল ১ টাকা হলে আসল = ১০০/১৩০ = ১০/১৩ সুদাসল ১০১৪ হলে আসল = (১০ × ১০১৪)/১৩ = ৭৮০ টাকা
