Which of the following cannot be the number of stamps in Sajib's collection?/সজীবের সংগ্রহের ডাকটিকিটের মধ্যে বাংলাদেশী ডাকটিকিট অন্য দেশের ডাকটিকিটের ৩ গুণ। নিচের কোনটি সজীবের সংগ্রহের ডাকটিটের সংখ্যা হতে পারেনা?
- A. 96
- B. 96
- C. 96
- D. 96
Answer: Option C
Explanation:
Stamps must be in an integer.
Let's say, he has x stamps of other countries
So, he has 3x Stamps of Bangladesh
So it has to be, x+3x=54 [In total]
But if we solve the equation, we can see that x=27/2, which is a fraction [not an integer]
So 54 cannot be the number of stamps. (ans)
