If "P" denotes "added to", "Q" denotes "subtracted from", "R" denotes "divided by" and "S" denotes "multiplied by", then which of the following equation is true?

If "P" denotes "added to", "Q" denotes "subtracted from", "R" denotes "divided by" and "S" denotes "multiplied by", then which of the following equation is true? Correct Answer 6 P 7 Q 12 R 6 S 3 = 7

Decoding given information:

After replacing letters by their respective signs:

1) 18 × 12 ÷ 4 + 5 – 6

= 18 × 3 + 5 – 6

= 54 + 5 – 6

= 59 – 6

= 53 ≠ 65

2) 4 + 57 ÷ 3 - 7 × 3

= 4 + 19 - 7 × 3

= 4 + 19 – 21

= 23 – 21

= 2 ≠ -2

3) 6 + 7 - 12 ÷ 6 × 3

= 6 + 7 - 2 × 3

= 6 + 7 – 6

= 13 – 6

= 7

4) 29 - 28 ÷ 2 + 3 × 2

= 29 - 14 + 3 × 2

= 29 - 14 + 6

= 35 - 14

≠ 21

Hence, the correct answer is ‘6 P 7 Q 12 R 6 S 3 = 7’.
