📌 Question 121
📝 Question
A wholesaler purchased 1,200 LED tube lights at ₹850 each. He spent ₹36,000 on transportation, ₹18,000 on insurance, and ₹24,000 on warehouse handling.
During transit, 80 tube lights were damaged and sold at 40% of their effective cost price. The remaining tube lights were sold through an online marketplace charging 6% commission on the selling price.
If the wholesaler earned an overall profit of 22%, find the selling price of each good tube light.
⚡ Shortcut Method
Purchase Cost
= 1200 × 850
= ₹10,20,000
Effective CP
= 10,20,000 + 36,000 + 18,000 + 24,000
= ₹10,98,000
Effective CP per Tube Light
= 10,98,000 ÷ 1200
= ₹915
Required Net SP
= 10,98,000 × 122%
= ₹13,39,560
Recovery from Damaged Stock
= 80 × (915 × 40%)
= ₹29,280
Net Amount Required
= 13,39,560 − 29,280
= ₹13,10,280
Let SP per Good Tube Light = ₹x
1120 × 94% × x = 13,10,280
x = 13,10,280 ÷ 1052.8
= ₹1,244.66
✅ Final Answer
₹1,244.66 per tube light
📌 Question 122
📝 Question

Find the retailer’s overall profit percentage.
⚡ Shortcut Method
Assume CP = ₹100
MP = ₹280
Final SP
= 280 × 0.85 × 0.80 × 0.90 × 0.94
= ₹160.8768
Profit
= 160.8768 − 100
= ₹60.8768
Profit %
= 60.88%
✅ Final Answer
60.88% Profit
📌 Question 123

If the dealer earned an overall profit of 18%, find the selling price of each good chair.
⚡ Shortcut Method
Purchase Cost

💡 Shortcut Trick of the Day
Convert Percentages into Factors
Instead of calculating percentages repeatedly, convert them into multiplication factors:
- 20% Profit = × 1.20
- 15% Loss = × 0.85
- 25% Discount = × 0.75
- 8% Commission = × 0.92
- 5% Cashback = × 0.95
Using factors significantly reduces calculation time in Banking exams.
