Explanation: Given: 14 P 4 S (16 Q 4) P 9 R (60 Q 6) P 7 S 20 = ? Given LetterPQRS New Sign ×÷ - + Using BODMAS rule. Operation preference wise Symbol Brackets [], , () Orders, of (power), √(root), of ​ Division ​ ÷ ​ ​ Multiplication × Addition + Subtraction − New equation: 14 × 4 + (16 ÷ 4) × 9 - (60 ÷ 6) × 7 + 20 = ? 14 × 4 + 4 × 9 - 10 × 7 + 20 = ? 56 + 36 - 70 + 20 = ? 92 - 70 + 20 = ? 112 - 70 = ? ? = 42 Thus, correct option is (b).

If ‘P’ stands for ‘×’, ‘Q’ stands for ‘÷’, ‘R’ stands for ‘-’ and ‘S’ stands for ‘+’, what will come in place of the question mark (?) in the following equation? 14 P 4 S (16 Q 4) P 9 R (60 Q 6) P 7 S 20 = ?
