What is the remainder when 38 is divided by 7?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 2.
Given, 38 = (34)2
Now, 34 = 81
When 81 is divided by 7, remainder = 4
Now (34)2 is divided by 7, remainder = (4)2 = 16
Finally, on dividing 16 by 7, remainder = 2
Hence the required answer is 2.
