If 'x' means 'addition', '-' means 'division','÷' means 'subtraction' and '+' means 'multiplication', then which of the equation is correct?
25 + 10 - 5 ÷10 x 3 =43
25 - 10 x 5 + 10 ÷ 3 = 72
25 x 10 ÷ 5 + 10 -3 = 12
25 ÷ 10 + 5 x 10 ÷3 = 18
A.
25 + 10 - 5 ÷10 x 3 =43
25 x 10 ÷ 5 - 10 + 3 = 43
On changing signs,
25 x 10 ÷ 5 - 10 + 3 = 43
25 x 2 - 10 + 3 = 43
50 - 10 + 3 = 43
40 + 3 = 43
43 = 43
