Correct Answer: 40

ধরা যাক মুরাদ x সংখ্যক ২০ পয়সা টিকেট এবং x সংখ্যক ৩০ পয়সা টিকেট কেনেছেন। একটি ২০ পয়সা টিকেটের দাম ০.২০ টাকা এবং একটি ৩০ পয়সা টিকেটের দাম ০.৩০ টাকা। সমস্ত টিকেটের মোট দাম ১০.০০ টাকা হলে, আমরা নিচের সমীকরণটি লেখতে পারি:0.20x + 0.30x = 10.00এই সমীকরণটি সহজ করতে, আমরা লিখতে পারি:0.50x = 10.00সুতরাং,x = 10.00 / 0.50x = 20তাই মুরাদ ২০টি ২০ পয়সা টিকেট এবং ২০টি ৩০ পয়সা টিকেট কেনেছেন, মোটমতে ৪০টি টিকেট কেনা হয়েছে।
