Option 3 : 8% Profit

Given:

Kamal uses 900 grams instead of 1000 grams for almonds

Kamal uses 1100 grams instead of 1000 grams for cashews

CP of almonds = Rs. 650/kg

CP of cashews = Rs. 900/kg

SP of almonds = Rs. 750/kg

SP of cashews = Rs. 950/kg

Formula Used:

Profit = SP - CP

Profit % = (Profit/CP) × 100

Calculation:

Machine weighs only 900 grams instead of 1 kg

Cost price of 900 grams almonds = Rs. (900/1000) × 650

⇒ Rs. 585

Selling price of 900 grams almonds = Rs 750

Machine 2 weighs 100 grams less

Cost price of 1100 grams of cashews = Rs. (1100/1000) × 900

⇒ Rs. 990

Selling price of 1100 grams of cashews = Rs. 950

Total cost price of almonds and cashews = Rs. (585 + 990)

⇒ Rs. 1575

Total selling price of almonds and cashews = Rs. (750 + 950)

⇒ Rs. 1700

Profit = SP - CP

⇒ Rs. (1700 - 1575)

⇒ Rs. 125

Profit % = (Profit/CP) × 100

⇒ (125/1575) × 100

⇒ 7.94% ≈ 8%

∴ In the whole transaction Kamal incurred a profit of 8%.
