If P denotes ‘+’, R denotes ‘x’, S denotes ‘-‘ and T denotes ‘÷’, then the value of5 R 9 P 7 S 9 T 3 P 6 is

54
55
60
59

The correct answer is (a) 54.

Following the given order of operations, we first multiply 5 and 9, then add 7, then subtract 9, then divide 3, and finally add 6. This gives us:

$5 R 9 P 7 S 9 T 3 P 6 = (5 \times 9) + 7 – (9 \div 3) + 6 = 45 + 7 – 3 + 6 = 54$

Here is a brief explanation of each option:

  • (a) 54: This is the correct answer, as explained above.
  • (b) 55: This is incorrect because 5 + 9 = 14, not 15.
  • (c) 60: This is incorrect because 5 x 9 = 45, not 60.
  • (d) 59: This is incorrect because 5 – 9 = -4, not 59.
