🔹 Q2. If the cost price of 15 items is equal to the selling price of 12 items, what is the profit percentage?

A. 20%
B. 25%
C. 30%
D. 15%

Solution:
Let CP of 1 item = ₹1 ⇒ CP of 15 items = ₹15
SP of 12 items = ₹15 ⇒ SP of 1 item = ₹15/12 = ₹1.25

A. 26%
B. 30%
C. 32%
D. 28%

Solution:
Let CP = ₹100
MP = 140
SP = 140 − 10% of 140 = 140 − 14 = ₹126
Profit = 126 − 100 = ₹26
Profit % = (26 / 100) × 100 = 26%

🔹 Q4. A man sells an article at a loss of 10%. If he had sold it for ₹60 more, he would have gained 5%. What is the cost price?

A. ₹400
B. ₹500
C. ₹600
D. ₹450

Solution:
Let CP = x
Then, SP1 = x − 10% of x = 0.9x
SP2 = x + 5% of x = 1.05x
Given: 1.05x − 0.9x = ₹60 → 0.15x = ₹60 → x = ₹400

✅ Answer: A. ₹400

🔹 Q5. A shopkeeper sells an article at 20% loss. If he had bought it at 10% less and sold for ₹10 more, he would have gained 10%. Find the cost price.

A. ₹100
B. ₹120
C. ₹125
D. ₹110

Solution:
Let CP = x
Then, SP = x − 20% of x = 0.8x
New CP = x − 10% of x = 0.9x
New SP = 0.8x + 10 = 1.1 × 0.9x = 0.99x
→ 0.8x + 10 = 0.99x
→ 10 = 0.19x
→ x = ₹52.63 (Does not match options)

Let’s try options: Try C. ₹125
Loss SP = 0.8×125 = 100
New CP = 125 − 12.5 = 112.5
New SP = 100 + 10 = 110
Check gain:
110 − 112.5 = −2.5 ⇒ Not correct

Try B. ₹120
SP = 0.8×120 = 96
New CP = 108
New SP = 106 ⇒ Gain = -2 → Wrong

Try A. ₹100
SP = 80
New CP = 90
New SP = 90 + 10 = 100
Gain = 10 ⇒ 10% gain on 90 ✔️

✅ Answer: A. ₹100
