Show answer & explanation

Correct answer: D

Explanation

The correct answer is Option 4 i.e. 5%.

Let the original price of the cell phone = Rs. 100

The price paid by Ram = 70% of 100 = Rs. 70

⇒ SP = CP×(100+P)100CP \times {(100 + P) \over 100} = 70×(100+50)10070 \times {(100 + 50) \over 100}

⇒ SP = 70×15010070 \times {150 \over 100}

⇒ SP = Rs 105

Profit % = 105−100100×100=5\frac{105-100}{100}\times100=5%
