Answer: Option A

Explanation:

Let, c = x ∴b = x + 10 and a = x + 12 Now,a + b + c = 130 = > x + 12 + x + 10 + x = 130 = > 3x = 130 - 22 = 108 ∴x = (108/3) = 36 i.e, c = 36 ∴ b = 46 and a = 48 ∴(b + c) - a = (46 + 36) - 48 = 34 Ans.

Answer: Option B

Explanation:

To achieve a 50/50 mixture of water and acid, you need to add an equal amount of water to the existing 10 ml of acid. Since you have 30 ml of the mixture, which already contains 10 ml of acid, you need to add an additional 10 ml of water (equal to the amount of acid) to balance it out. So, the answer is 10 ml.

Answer: Option D

Explanation:

Let's track the bus's movements step by step:

The bus travels 2 blocks north.
Then, it travels 2 blocks east.
Next, it goes 1 block south.
Afterward, it continues 2 blocks east.
Finally, it moves 1 block south.

Now, let's see where the bus is in relation to the hotel:

It went 2 blocks north initially but then moved 1 block south, so it's still 1 block north of the starting point.
It went 2 blocks east and then 2 blocks east again, which adds up to 4 blocks east of the starting point.

So, the bus is 1 block north and 4 blocks east of the hotel. Therefore, the answer is 4 blocks east.
