Question 1

Which two numbers should be interchanged in the following equation to make it correct?
$$618 + 37 \times 12 - 703 \div 14 = 767$$

Solution

By trial and error method,

Option A

$$618+12\times37-703\div14=767$$

703 is not divisible by 14 so we get a decimal number after solving which is not possible

Option B

$$618+37\times703-12\div14=767$$

12 is not divisible by 14 so we get a decimal number after solving which is not possible

Option C

$$618+14\times12-703\div37=767$$

$$618+14\times12-19=767$$

$$618+168-19=767$$

$$767=767$$

Hence, the correct answer is Option C
