If P means 'minus' (-), Q means 'plus' (+), R means 'multiplied by' (×), and S means 'divided by' (÷), then what is the value of the following expression?
100 S 5 R 2 P 10 Q 4
Show answer & explanation
Correct answer: A
Explanation
Given:
P = −, Q = +, R = ×, S = ÷
After substitution:
100 ÷ 5 × 2 − 10 + 4
Solve according to BODMAS rule,
= 100 ÷ 5 × 2 − 10 + 4
= 20× 2 – 6
= 40-6
= 34
Hence, the correct answer is option 1.
