Question : Directions: In the following question, correct the equation by interchanging two signs. 43 + 9 – 6 ÷ 3 × 8 = 50
Option 1: ÷ and ×
Option 2: + and ÷
Option 3: – and +
Option 4: – and ×
Correct Answer: – and +
Solution : Given: 43 + 9 – 6 ÷ 3 × 8 = 50
Replace the given signs in the options one by one with those in the given equation. First option: ÷ and × = 43 + 9 – 6 × 3 ÷ 8 = 43 + 9 – 6 × 0.375 = 43 + 9 – 2.25 = 49.75 ≠ 50 Second option: + and ÷ = 43 ÷ 9 – 6 + 3 × 8 = 4.78 – 6 + 3 × 8 = 4.78 – 6 + 24 = 22.78 ≠ 50 Third option: – and + = 43 – 9 + 6 ÷ 3 × 8 = 43 – 9 + 2 × 8 = 43 – 9 + 16 = 50 Fourth option: – and × = 43 + 9 × 6 ÷ 3 – 8 = 43 + 9 × 2 – 8 = 43 + 18 – 8 = 53 ≠ 50
Here, only the third option satisfies the R.H.S. of the given equation. Hence, the third option is correct.
