Given:

The length of the hall is 5 mt more than the breadth of the hall.

Explanation:

Let's take breadth as x

The length will be x + 5

Area of rectangle = length × breadth

84 = (x+5) × x

x² + 5x – 84 = 0

x = -12 or x = 7

The length of any object will be in positive integers so x = 7

If the breadth is 7, then the length is 12.

∴The length and breadth of the hall are 12 mt and 7 mt respectively.

Explanation:

The cost price of the first saree, where the seller made a profit of 20%, can be calculated as:

Selling Price / (1 + Profit%) = 400 / (1 + 20/100) = Rs. 333.33

The cost price of the second saree, where the seller made a loss of 20%, can be calculated as:

Selling Price / (1 - Loss%) = 400 / (1 - 20/100) = Rs. 500

So, the total cost price for the two sarees is Rs. 833.33.

The total selling price for the two sarees is Rs. 800 (since each saree was sold for Rs. 400).

The overall loss is the difference between the total cost price and the total selling price, which is Rs. 33.33.

The loss percentage can be calculated as:

(Loss / Total Cost Price) * 100 = (33.33 / 833.33) * 100 ≈ 4%

So, the seller made an overall loss of about 4%.

Given:

In a mixture of Dettol and water, the water is 80%.

Explanation:

Initial Dettol to water ratio: 1 : 4

Final Dettol to water ratio: 1 : 3

There is no change in water.

So need to equate the water in both the ratios

Then, the ratios will be-

Initial Dettol to water ratio: 3 : 12

Final Dettol to water ratio: 4 : 12

Change in Dettol is 1 part.

The total initial volume is 15 parts = 60 ltr

1 part = 4 liter

So, the Change in Dettol is 1 × 4 liter

= 4 liter

∴Dettol added to the mixture is 4 liters.
