Q8DSSSB TGT Computer Science, 7 Feb 2024, Shift 2 (12:30 PM)
The breadth of a rectangular hall is 5/8 of its length. If the area of the floor is 160 metre², then what is the difference between the length and breadth of the hall?
  1. A8 metre
  2. B6 metre
  3. C10 metre
  4. D4 metre
Show answerHide answer

Correct answer: (B) 6 metre
