If '÷' means '+', '-' means 'x', '+' means '-' and, 'x' means '÷', then which of the following equations is CORRECT?

A42 × 28 - 30 ÷ 48 + 45 = 45

B42 × 28 - 30 ÷ 48 + 45 = 50

C42 × 28 - 30 ÷ 48 + 45 = 40

D42 × 28 - 30 ÷ 48 + 45 = 48

Answer:

D. 42 × 28 - 30 ÷ 48 + 45 = 48

Read Explanation:

Replace the symbols according to the given meanings:

  • × means ÷

  • − means ×

  • ÷ means +

  • + means −

So,

42 × 28 − 30 ÷ 48 + 45

becomes

42 ÷ 28 × 30 + 48 − 45

Now apply BODMAS:

  • (42 ÷ 28 = 1.5)

  • (1.5 × 30 = 45)

  • (45 + 48 = 93)

  • (93 − 45 = 48)

Thus,

42 × 28 − 30 ÷ 48 + 45 = 48

Correct option: 42 × 28 − 30 ÷ 48 + 45 = 48 (Option D)
