Select the correct combination of mathematical signs that can sequentially replace the * signs and balance the given equation.

364 * 4 * 7 * 4 * 12 = 75

If ‘÷’ means ‘-’, ‘-’ mean ‘+’, ‘+’ means ‘×’ and ‘×’ means ‘÷’, compute the value of the expression:

Which among the given operators should replace the “%” (in the same order) in the given expression below:

6 % 11 % 6 % 37 % 30 % 7

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

11 – 22 + 30 × 25 ÷ 5 = 267

If "+" means "subtraction", "×" means "division", "÷" means "addition" and "–" means "multiplication", then solve 98 – 2 x 14 ÷ 5 – 7 + 40 .

Select the correct combination of the mathematical signs to replace the ‘@’ symbols in the below equation and thereby balance it:

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' = ?
