10 - 8 × 2 ÷ 4 + 6 = 0

  1. AOption (a)

    ×, -

  2. BOption (b)

    ×, ÷

  3. COption (c)

    ÷, -

  4. DOption (d)

    ×, +

View answer & explanation

Correct answer

Answer: (b)B.

×, ÷

Why this answer is correct

  1. ×, -

Given equation: 10 - 8 × 2 ÷ 4 + 6 = 0

After interchanging the signs, we get:

L.H.S = 10 × 8 - 2 ÷ 4 + 6

= 80 – 0.5 + 6

= 86 – 0.5

= 85.5 ≠ R.H.S

2) ×, ÷

Given equation: 10 - 8 × 2 ÷ 4 + 6 = 0

After interchanging the signs, we get:

L.H.S = 10 - 8 ÷ 2 × 4 + 6

= 10 – 4 × 4 + 6

= 16 – 16

= 0 = R.H.S

  1. ÷, -

Given equation: 10 - 8 × 2 ÷ 4 + 6 = 0

After interchanging the signs, we get:

L.H.S = 10 ÷ 8 × 2 - 4 + 6

= 2.5 – 4 + 6

= 8.5 – 4

= 4.5 ≠ R.H.S

  1. ×, +

Given equation: 10 - 8 × 2 ÷ 4 + 6 = 0

After interchanging the signs, we get:

L.H.S = 10 - 8 + 2 ÷ 4 × 6

= 10 – 8 + 3

= 13 – 8

= 5 ≠ R.H.S

Hence, ‘×, ÷’ is the correct answer.
