Question 49

Select the correct combination of mathematical signs to sequentially replace the * signs and to balance the following equation.
11 * 15 * 78 * 6 * 18 * 160

By Trial and Error method,

Option A

$$11+15\times78-6\div18=160$$

$$11+15\times78-\frac{1}{3}=160$$

We get decimal value after solving which is not possible. Hence Option A is incorrect.

Option B

$$11\times15+78\div6-18=160$$

$$11\times15+13-18=160$$

$$165+13-18=160$$

$$160=160$$

Hence, the correct answer is Option B
