​What will come in the place of ' ? 'in the following equation. if ’ + ’ and ’ - ’ are interchanged and also'$$\times$$’ and ’ $$\div$$​ ’ are interchanged?

$$60 - 72 \times 6 + 15 \div 3 = ?$$​

Given:

if ’ + ’ and ’ - ’ are interchanged and also'’ and ’ $$\times$$​$$\div$$​ ’ are interchanged

then modifies equation will be:

= 60 + 12 - 15 × 3

= 60 + 12 - 45

= 72 - 45

Thus, Option A is the correct answer.
