✤ 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.
