Remark
The order is not quite correct.
- 7 + (-11 * 5 - - 7) ÷ - 6
The - - 7 becomes a plus
- 7 + (- 55 + 7) ÷ -6
This is where the real problem is. -55 + 7 goes down. This gives - 48
- 7 + [( - 48) ÷ - 6]
You do the division by - 6 before adding. Adding - 7 to the result of the division is your very last step. Think BedMas.
-7 + (8)
The 8 is the result of the division. -48/-6 = 8. the -7 and the 8 are added. You get 1.

C. Between E and F and between G and H the elevator could be travelling from a higher floor to a lower floor.
<u>We have to justify all the options with respect to the </u><u>graph </u><u>:-</u>
<u>Option A</u> : Between A and B, the elevator would be travelling from a lower floor to a higher floor. Also between C and D, the elevator would be travelling from a lower floor to a slightly higher floor.
So, this option is <u>not correct.</u>
<u>Option B</u> : Between B and C, the elevator wouldn't go higher. And also the same would happen in between D and E.
So, this option is <u>not correct.</u>
<u>Option C</u> : Between E and F, the elevator would be travelling from higher floor to lower and also between G and H.
So, this option is <u>correct</u>.
<u>Option 4</u> : Between F and G, there would not have much changes. So it will be omitted.
So, this option is <u>not correct.</u>
