If ‘z’ denotes ‘addition’, ‘x’ denote ‘multiplication’, ‘y’ denotes ‘division’, and ‘w’ denotes ‘subtraction’, then what will be the value of the following expression?
3.2z(0.56 y 1.4 x 4) w 5 x 5 y 25 z 5.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 8.8.
Given equation: 3.2 z (0.56 y 1.4 x 4) w 5 x 5 y 25 z 5
On replacing the letters:
3.2 + (0.56 ÷ 1.4 × 4) - 5 × 5 ÷ 25 + 5
3.2 + 1.6 - 1 + 5
9.8 - 1 = 8.8
