Question 6

# Which two signs should be interchanged in the following equation to make it correct?$$207 \times 9 + 13 \div 26 - 301 = 60$$

Solution

By trial and error method,

Option A

$$207\times9-13\div26+301=60$$

$$207\times9-\frac{1}{2}+301=60$$

Option A is false since we get decimal number after solving

Option B

$$207+9\times13\div26-301=60$$

$$207+9\times\frac{1}{2}-301=60$$

Option B is also false since we get decimal number after solving

Option C

$$207\div9+13\times26-301=60$$

$$23+13\times26-301=60$$

$$23+338-301=60$$

$$60=60$$

Hence, the correct answer is Option C
