In a coded inequality, '●' means '>', '○' means '<', '□' means '=', '★' means '≥' and '◆' means '≤'. For the statement 'M ● N □ O', consider: I. M ● O
II. M ★ O. Which conclusion(s) are definitely true?

Competition practiceInequalities
  • AOnly II follows
  • BNeither follows
  • CBoth I and II follow
  • DOnly I follows

Step-by-Step Solution

M > N and N = O give M > O, so 'M ● O' is true; and M > O also makes 'M ★ O' (M ≥ O) true.
Answer: C) Both I and II follow
