What will come in place of the ‘?’ in the following equation, if ‘+’ and ‘−’ are interchanged and ‘×’ and ‘÷’ are interchanged? 231 ÷ 61 × 427 − 321 + 217 = ?
137
Swapping ÷ with × and − with + turns the expression into 231×61÷427+321−217; computing gives 231×61=14091, 14091÷427=33, then 33+321−217=137. Hence, 137 is correct.
