📌 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
Effective CP = ₹10,98,000
Overall required recovery:
₹10,98,000 × 122% = ₹13,39,560
Damaged stock recovery:
80 × ₹915 × 40% = ₹29,280
Amount required from good stock:
₹13,39,560 − ₹29,280 = ₹13,10,280
Good stock = 1,120
After 6% commission, wholesaler receives 94% of SP.
So:
1,120 × 94% × x = ₹13,10,280
x = ₹1,244.5669
Therefore the correct answer is:
₹1,244.57 per tube light
✅ Final Answer
₹1,244.57 per tube light
📌 Question 122
📝 Question
A retailer marks an article 180% above its cost price. During a festive sale, he offers successive discounts of 15%, 20%, and 10%. After the purchase, the customer receives a cashback equal to 6% of the billed amount.
Find the retailer’s overall profit percentage.
⚡ Shortcut Method
Take CP = ₹100.
Markup 180%:
MP = ₹280
After 15% discount:
₹280 × 85% = ₹238
After 20% discount:
₹238 × 80% = ₹190.40
After 10% discount:
₹190.40 × 90% = ₹171.36
Cashback = 6% of billed amount:
₹171.36 × 94% = ₹161.0784
Profit:
₹161.0784 − ₹100 = ₹61.0784
Therefore:
Profit = 61.08%
✅ Final Answer
61.08% Profit
📌 Question 123
📝 Question
A furniture dealer purchased 360 office chairs at ₹3,500 each. He spent ₹48,000 on transportation and ₹24,000 on packaging.
Out of the total stock, 24 chairs were damaged and sold at 50% of their effective cost price. The remaining chairs were sold through a dealer who charged 5% commission on the selling price.
If the dealer earned an overall profit of 18%, find the selling price of each good chair.
⚡ Shortcut Method
Effective CP:
₹12,60,000 + ₹48,000 + ₹24,000
= ₹13,32,000
CP per chair:
₹13,32,000 ÷ 360 = ₹3,700
Required total recovery:
₹13,32,000 × 118% = ₹15,71,760
Damaged chairs recovery:
24 × ₹3,700 × 50%
= ₹44,400
Required recovery from good chairs:
₹15,71,760 − ₹44,400
= ₹15,27,360
Good chairs = 336
After 5% commission:
336 × 95% × x = ₹15,27,360
x = ₹4,784.96
✅ Final Answer
₹4,784.96 per chair
📌 Question 124

During transit, 50 earbuds were damaged and sold at 35% of their effective cost price. The remaining earbuds were sold through an e-commerce platform charging 7% commission on the selling price.
If the dealer earned an overall profit of 24%, find the selling price of each good earbud.
⚡ Shortcut Method
Effective CP:
₹12,80,000
CP per earbud:
₹1,600
Required recovery:
₹12,80,000 × 124% = ₹15,87,200
Damaged stock recovery:
50 × ₹1,600 × 35% = ₹28,000
Required from good earbuds:
₹15,87,200 − ₹28,000 = ₹15,59,200
Good earbuds = 750
After 7% commission, seller receives 93%.
750 × 93% × x = ₹15,59,200
x = ₹2,235.41
✅ Final Answer
₹2,235.41 per earbud
📌 Question 125
📝 Question
A retailer purchased 1,250 electric kettles at ₹1,600 each. He spent ₹75,000 on transportation and ₹50,000 on insurance.
During transit, 50 kettles were damaged and sold at 40% of their effective cost price. Of the remaining kettles, 20% were sold at 15% profit, while the rest were sold through an online platform charging 5% commission on the selling price.
If the retailer earned an overall profit of 18%, find the selling price of each kettle sold through the online platform.
⚡ Shortcut Method
Purchase Cost
= 1,250 × 1,600
= ₹20,00,000
Effective CP
= 20,00,000 + 75,000 + 50,000
= ₹21,25,000
Effective CP per Kettle
= 21,25,000 ÷ 1,250
= ₹1,700
Required Net SP
= 21,25,000 × 118%
= ₹25,07,500
Recovery from Damaged Kettles
= 50 × (1,700 × 40%)
= ₹34,000
Good kettles remaining
= 1,250 − 50
= 1,200
Kettles sold at 15% profit
= 1,200 × 20%
= 240
Recovery from these kettles
= 240 × (1,700 × 115%)
= ₹4,69,200
Net Amount Required from Online Sales
= 25,07,500 − 34,000 − 4,69,200
= ₹20,04,300
Online-sale kettles
= 1,200 − 240
= 960
After 5% commission, retailer receives 95% of SP.
Let SP per online-sale kettle = ₹x
960 × 95% × x = 20,04,300
912x = 20,04,300
x = ₹2,197.70
✅ Final Answer
₹2,197.70 per kettle

- The remaining shirts were sold at 30% profit on the effective cost price.
- The wholesaler paid 8% commission on the selling price to an online marketplace.
Find the overall profit percentage.
⚡ Shortcut Method
Your calculation:
Effective CP = ₹5,70,000
CP per shirt = ₹950
Damaged recovery = ₹17,100
Good shirts:
560 × ₹950 × 130% × 92%
= ₹6,36,272
Total recovery:
₹6,36,272 + ₹17,100
= ₹6,53,372
Profit:
₹6,53,372 − ₹5,70,000
= ₹83,372
Profit percentage:
₹83,372 ÷ ₹5,70,000 × 100
= 14.63%
✅ Final Answer
14.63% Profit

⚡ Shortcut Method
Purchase Cost
= 1,000 × 2,400
= ₹24,00,000
Effective CP
= 24,00,000 + 80,000 + 40,000 + 30,000
= ₹25,50,000
Effective CP per Speaker
= 25,50,000 ÷ 1,000
= ₹2,550
Required Net SP
= 25,50,000 × 115%
= ₹29,32,500
Recovery from Damaged Speakers
= 60 × (2,550 × 50%)
= ₹76,500
Recovery from Clearance Sale
= 240 × (2,550 × 88%)
= ₹5,38560
Remaining Speakers
= 1,000 − 60 − 240
= 700
Net Amount Required from Remaining Speakers
= 29,32,500 − 76,500 − 5,38,560
= ₹23,17,440
After 6% commission, retailer receives 94% of SP.
Let SP per remaining speaker = ₹x

💡 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.
