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

What will be the value of expression if the numbers/digits ‘(30)’ and ‘(13)’ are interchanged?

78 ÷ 30 × 6 + 13 - 14 + 12

If 34 – 28 means 952, 544 + 8 means 68, 20 ÷ 5 means 25, 20 x 10 means 10, then 375 – 11 x 270 ÷ 550 + 11 x 35 = ?
