Which of the following interchanges in two mathematical operators will balance the equation given below? 75 ÷ 15 × 8 + 14 − 5 = 67

Swapping ÷ and ×: 75 × 15 ÷ 8 + 14 − 5 is messy. Let's try swapping + and −: 75÷15×8−14+5=5×8−14+5=40−14+5=31≠67. Try swapping ÷ and ×: 75×15÷8+14−5 not integer. Try − and ×: 75÷15−8+14×5=5−8+70=67. Yes! Swapping − and × gives 67. Answer is (c) − and ×.
