Question 34

Select the correct combination of mathematical signs to replace the sign () and balance the following equation.
15 4 * 26 * 2 * 7 * 66

Solution

By Trial and Error method,

Option A

$$15+4\times26-2\div7=66$$

$$15+4\times26-\frac{2}{7}=66$$

After solving the value will be decimal which is not possible

Option B

$$15+4\times26\div2-7=66$$

$$15+4\times13-7=66$$

$$15+52-7=66$$

$$60=66$$

Hence Option B is incorrect

Option C

$$15\times4+26\div2-7=66$$

$$15\times4+13-7=66$$

$$60+13-7=66$$

$$66=66$$

Hence, the correct answer is Option C
