Cashew nut is very adaptable with respect to soil conditions required for growing. It can grow even in poor soil. However, the best soils for growing cashew nuts are deep and well drained loamy soil. Cashew nut also grows well on sandy soil.

Monthly salary = Rs. 7000
Then money earned in the 1st year = 7000*12 = Rs. 84000
Annual increment = Rs. 500
Money earned in the 2nd year with increment =7500*12 = Rs. 90000
Now for 3rd year = 8000*12 = Rs.96000
So, here
a = Rs. 84000
d = Rs. 6000
n = 10 years
Sn = n/2{2a + (n - 1)d}
S₁₀ = 10/2{2*84000 + (10 - 1)6000}
= 5{168000 + 54000}
= 5*222000
= Rs.1110000

Types of decomposition reaction
Let us look at the three main types of decomposition reactions which we see around us.
-
- Thermal decomposition reaction A thermal decomposition reaction can be defined as a decomposition reaction which is activated by thermal energy. The reaction is generally endothermic as energy is required to break chemical bond in order to separate the constituent elements.
- example of thermal decomposition reaction
- CaCO3 → CaO + CO2 When heated Calcium Carbonate,decomposes into Calcium Oxide and Carbon Dioxide. This process is employed in the manufacturing of quick lime which is an important component in industries.

- Electrolytic decomposition reaction
-
-
- An electrolytic decomposition reaction is a type of decomposition reaction in which the activation energy for decomposition. Example of electrolytic decomposition reaction
- Dissociation of water:2H2O→ 2H2 + O2
- An electrolytic decomposition reaction is a type of decomposition reaction in which the activation energy for decomposition. Example of electrolytic decomposition reaction
-
- Photo decomposition/ photolytic decomposition/ photochemical decomposition
-
- A photo decomposition is the type of decomposition reaction in which the reactant is broken down to its constituents by photons.Example of photo decomposition reaction
- O3 + hν → O2 + O(1D)Photolysis occurs in the atmosphere wherein ozone molecules is broken down into oxygen molecule and atomic oxygen.

Those reactions in which two compounds react by an exchange of ions to form two new compounds are called double displacement reactions.
Example: AgNO3 (aq) + NaCl (aq) {tex}\rightarrow{/tex} AgCl (s)+ NaNO3 (aq)
When silver nitrate solution is added to sodium chloride solution, then a white precipitate of silver chloride is formed alongwith sodium nitrate solution. In this reaction, two compounds, silver nitrate and sodium chloride, react to form two new compounds, silver chloride and sodium nitrate.
