Which two numbers should be interchanged to make the given equation correct?
$$7 + 24 \times 3 - 72 \div 18 = 58$$
By Trial and Error method,
Option A
$$3+24\times7-72\div18=58$$
$$3+24\times7-4=58$$
$$3+168-4=58$$
$$167=58$$
Hence Option A is incorrect
Option B
$$7+18\times3-72\div24=58$$
$$7+18\times3-3=58$$
$$7+54-3=58$$
$$58=58$$
Hence, the correct answer is Option B
