If the integer x is divisible by 5 but not by 2, then which one of the following is never an integer ?

A x+12
B x3/3
C x2/3
D x6

Correct Answer: x6

একটি পূর্ণসংখ্যা যা 5 দ্বারা বিভাজ্য কিন্তু 2 দ্বারা বিভাজ্য নয় এমন সংখ্যাগুলো হলো, 5, 15, 25, 35…… ইতাদি। এখন, x = 15 বিবেচনা করি a, 15  + 18 = 8, যা একটি পূর্ণসংখ্যা। b. (15)3  3 =  33753 = 1125 যা একটি পূর্ণসংখ্যা। c. 152 3 =  1153 = 75 , যা একটি পূর্ণসংখ্যা। d. 15 6 = 2.5, যা একটি পূর্ণসংখ্যা নয়। সুতরাং x 6 পূর্ণসংখ্যা নয়।
