Correct Answer - Option 1 : Only I

**Given: **

CP of rice = 120 Rs/kg

SP of rice = 150 Rs/kg

He is giving only 800 gm of rice instead of 1 kg

**Formula Used: **

Profit = SP – CP

Profit% = (Profit/CP) × 100

SP = {(100 + P%)/100} × CP

Where P is Profit, CP is cost price and SP is selling price.

**Calculation:**

He is giving only 800 gm of pulse instead of 1 kg while selling

Cost price of 1000gm = 120 Rs/kg

Cost price of 800gm = (120/1000) × 800

⇒ 96 Rs/kg

Effective cost price = 96 Rs.

SP = 150 Rs/kg

⇒ SP – CP = 150 – 96

⇒ 54 Rs/kg

Profit% = (54/96) × 100

⇒ **Profit%**** = 56.25%**

I. Profit made by the shopkeeper is 56.25%

⇒ Profit% = 56.25%

⇒ **I is correct**

II. Profit on 2 kg pulse is Rs. 100

Profit = 54 Rs/kg

Profit on 2 kg = 54 × 2

⇒ Rs. 108

⇒ II is incorrect
