Answer:
Answer:
Present age of Anupama is 6 years.
Present age of her mother is 42 years.
Step-by-step explanation:
Given :
Ratio of present ages of Anupama and her mother is 1:7 .
After 2 years, ratio is 2:11.
To find :
Present ages of Anupama and her mother.
Solution :
Let, Present age of Anupama be 1x or x .
• Ratio of present ages of Anupama and her mother is 1:7.
Therefore, Present age of her mother be 7x .
After 2 years :
Anupama's age = x + 2
Her mother age = 7x + 2
Ratio of their ages after 2 years is 2:11. So,
\implies \sf \dfrac{x + 2}{7x + 2} = \dfrac{2}{11}⟹
7x+2
x+2
=
11
2
\implies \sf 11 \times (x + 2) = 2 \times (7x + 2)⟹11×(x+2)=2×(7x+2)
\implies \sf 11x + 22 = 14x + 4⟹11x+22=14x+4
\implies \sf 11x + 22 - 4 = 14x⟹11x+22−4=14x
\implies \sf 11x + 18 = 14x⟹11x+18=14x
\implies \sf 18 = 14x - 11x⟹18=14x−11x
\implies \sf 18 = 3x⟹18=3x
\implies \sf \dfrac{18}{3} = x⟹
3
18
=x
\implies \pmb{\sf x = 6}⟹
x=6
x=6
Anupama's age = x = 6 years.
Her mother age = 7x = 7 × 6 = 42 years.
Hence,
Present age of Anupama is 6 years and Present age of her mother is 42 years.
Common Types of Weather Element s
The weather has a lot of different factors. When someone asks how the weather is today, you need to think about temperature, humidity, precipitation, wind, cloudiness, and atmospheric pressure. All these different parts work together to create the weather you see when you walk out the door.
But, what do each of these weather examples mean? Find out by reading about each one.
Temperature
It’s getting hot out there. When you talk about the heat of the air outside on a summer day, this is the temperature. Measured with a thermometer in Fahrenheit, Celsius, or Kelvin, the temperature tells you how fast the air molecules and atoms are moving. Fast-moving molecules and atoms mean the temperature is high, while slow-moving molecules in
Is the air dry? The moisture or dryness of the air is humidity. It’s an important weather aspect. Without it, humans wouldn’t be able to survive. However, the amount of water vapor, or humidity, in the air needs to have balance. Too little or too much water vapor in the air causes health issues and can be dangerous.
Precipitation
Precipitation is just a big word to describe how water falls to the ground. It can be rain, snow, sleet, ice, hail, or drizzle. The form these water or solid particles take depends on other weather factors. For example, if the temperature is cold, below 32 degrees, precipitation comes to the surface in the form of snow. If the weather is nice and warm, water comes down in the air create a low temperature

Cloudiness
Watching the different shapes of clouds roll by is one of the fun things about summer. Ever wonder what they are? Clouds are collections of water droplets in the air due to the cycle of water. Billions of water droplets are necessary to make a cloud. The four main types of clouds include cumulus, stratus, cirrus, and cumulonimbus.
Atmospheric Pressure
Air has weight! All those molecules and atoms add to the weight and push down. The weight of the air pushing down on the Earth’s surface is the atmospheric pressure. Since it’s measured using a barometer, it’s also called barometric pressure.
Types of Severe Weather Conditions
The six common types of weather create all weather conditions. With the right humidity, wind, atmospheric pressure, temperature, clouds, and precipitation, a rainstorm happens. However, the most impactful weather conditions are severe weather. Learn about the different types of severe weather examples.
Thunderstorms
Produced by cumulonimbus clouds, thunderstorms include rain, hail, thunder, lightning, and gusty winds. Thunderstorms can be mild or severe.
Tornados
When a warm air front collides with a cold air front, it creates a narrow rotating column of air from a thunderstorm. Tornadoes come in different severities, measured on the Fujita scale, from the minor F0 to the major F6.

Wind
Air moves. All you must do is walk out your door to feel that. The movement of air is created by how the sun heats the Earth, and then convection tells you how air moves in predictable patterns. Therefore, meteorologists have some idea of how a storm will move or the type of weather you’ll have in a week.
