Question : Directions: In the following question, you have to identify the correct response from the given premises stated according to the following symbols: If – stands for +; + stands for × and × stands for –; then which one of the following equations is not correct?
Option 1: 22 + 7 – 3 × 9 = 148
Option 2: 33 × 5 – 10 + 20 = 228
Option 3: 7 + 28 – 3 × 52 = 127
Option 4: 44 – 9 + 6 × 11 = 87
Correct Answer: 7 + 28 – 3 × 52 = 127
Solution : Given: – stands for +; + stands for × and × stands for –.
Let's check the options – First option: 22 + 7 – 3 × 9 = 148 On replacing ⇒ 22 × 7 + 3 – 9 = 148 Solving the L.H.S. of the equation – = 22 × 7 + 3 – 9 = 154 + 3 – 9 = 157 – 9 = 148 = R.H.S. Second option: 33 × 5 – 10 + 20 = 228 On replacing ⇒ 33 – 5 + 10 × 20 = 228 Solving the L.H.S. of the equation – = 33 – 5 + 10 × 20 = 33 – 5 + 200 = 233 – 5 = 228 = R.H.S. Third option: 7 + 28 – 3 × 52 = 127 On replacing ⇒ 7 × 28 + 3 – 52 = 127 Solving the L.H.S. of the equation – = 7 × 28 + 3 – 52 = 196 + 3 – 52 = 199 – 52 = 147 ≠ 127 Fourth option: 44 – 9 + 6 × 11 = 87 On replacing ⇒ 44 + 9 × 6 – 11 = 87 Solving the L.H.S. of the equation – = 44 + 9 × 6 – 11 = 44 + 54 – 11 = 98 – 11 = 87 = R.H.S.
So, only the third option doesn't satisfy the R.H.S. of the given equation. Hence, the third option is correct.
