Answer:
₹14000
Step-by-step explanation:
Let c represent the cost price, and m represent the marked price.
c × (1 +40%) = m
m × (1 -15%) - c = ₹1900
Using the first expression for m, the second equation becomes ...
1.40c×0.85 -c = ₹1900
0.19c = ₹1900
c = ₹1900/0.19 = ₹10000
Then the marked price was ...
m = 1.40c = 1.40×₹10000 = ₹14000
The marked price was ₹14000.
_____
The selling price was ₹11900.
Answer:
It's heavy cream
Step-by-step explanation:
Homogenized milk has a density of 1.032 kg/L and
heavy cream has a density of 1.005 kg/L at 10°C.
At 10°C, a container holding 8 liters of liquid weighs 8.04 kilograms
To determine which container hold homogenized milk or heavy cream and How I know?
We findo the density of the measurements given and whatever it correspond to is what it is
First mass is 8.04kg
Liquid contained is 8 litres
SInce the density is kg/L
No need for conversion
Density = mass/volume = 8.04/8= 1.005kg/L
Heavy cream has a density of 1.005 kg/L at 10°C.
Therefore it correspond
