Answers
Answer:
Let us take the example of an ionic compound MgCl2. it consists of cation Mg2+and anion Mg in its pore from consist two extra electrons on of the other hand chlorine is short of one electron to complete its octet.
Hence one magnesium and two chlorine come together to transfer electrons between them and from the ionic compound. Formation of all ionic compounds take place in similar fashion.
Three general properties of ionic compounds are as follows:
1) soluble in polar solvents and insoluble in organic solvents.
2) Good conductor in molten from but non-conductor in solid forms.
3) Generally found in crystalline solid forms due to strong force of interaction.

✤ Required Answer:
✒ GiveN:
Cost price of a fan = Rs. 1200
Gain % = 8 %
✒ To Find:
Selling price of the fan....?
━━━━━━━━━━━━━━━━━━━━
✤ How to solve?
For solving this question, Let's note down some important formulae:
Selling price = Cost price + Gain/Profit
And, Profit % = Profit/CP × 100
Or else, Direct formula,
\large{ \boxed{ \rm{SP = \frac{CP(100 + p\%)}{100} }}}
SP=
100
CP(100+p%)
☃️ So, Let's try both the formulae, and solve the question
━━━━━━━━━━━━━━━━━━━━
✤ Solution:
Method 1:
We have,
Cost price = Rs. 1200
Gain % = 8 %
Finding gain/profit,
➝ Gain % = Gain/CP × 100
➝ 8 = Gain/1200 × 100
➝ 8 = Gain/12
➝ Gain = Rs. 96
Finding Selling price,
➝ Selling price = Cost price + Gain
➝ Selling price = Rs. 1200 + Rs. 96
➝ Selling price = Rs. 1296
☀️ Selling price of the fan = Rs. 1296
Method 2:
By using shortcut formula,
➝ Selling price = Cost price(100 + Gain%)/100
➝ Selling price = 1200(100 + 8)/100
➝ Selling price = 12 × 108
➝ Selling price = Rs. 1296
☀️ Here also, SP of the fan = Rs. 1296 only.
