If X means 'plus' (+), Y means 'divided by' (÷), Z means 'multiplied by' (×), and W means 'minus' (-), then what is the value of the following expression?
28 Y 4 Z 3 W 5 X 11
Show answer & explanation
Correct answer: C
Explanation
Given:
X = +, Y = ÷, Z = ×, W = −
Expression:
28 Y 4 Z 3 W 5 X 11
After substitution:
28 ÷ 4 × 3 − 5 + 11
Solve according to BODMAS rule:
= 28 ÷ 4 × 3 − 5 + 11
= 7× 3 + 6
= 21 +6
= 27
Hence, the correct answer is option 3.
