If 22 – 16 means 352, 450 + 50 means 9, 9 ÷ 3 means 12, 11 x 8 means 3, then ' 280 – 5 x 240 ÷ 450 + 9 x 26' = ?

If we interchange 2 and 1, then what will be the resultant of the given equation?

21+ 18 ÷ 6 × 12 – 7 = ?

Which two signs should be interchanged to make the following equation correct?

If '+' means '÷', '-' means ' X ', ' X ' means '+', '÷' means '-', what will come in place of the question mark(?)?

If '+' means '–', '–' means '×', '÷' means '+' and '×' means '÷', then ' 30 – 12 + 20 × 10 ÷ 10 ' = (?)

By interchanging the given two numbers (not digits), which of the following equations will be correct?

24 and 15

Which of the following interchange of numbers and mathematical signs would make the given equation correct?
