Question 45

Which two signs and numbers should be interchanged to make the following equation correct?

$$16 \times 18 + 2 - 14 \div 3 = 38$$

Solution

By Trial and Error method,

Option A

$$16\times14-2+18\div3=38$$

$$16\times14-2+6=38$$

$$224-2+6=38$$

$$228=38$$

Hence Option A is incorrect

Option B

$$14-18+2\times16\div3=38$$

$$14-18+2\times\frac{16}{3}=38$$

After solving the value will be decimal which is not possible

Option C

$$16+14\times2-18\div3=38$$

$$16+14\times2-6=38$$

$$16+28-6=38$$

$$38=38$$

Hence, the correct answer is Option C
