Question

एक व्यापारी को ₹360 में एक घड़ी बेचने से 10 परसेंट हानि होती है यदि वह 5% लाभ चाहता है तो बड़ी घड़ी का विक्रय मूल्य ज्ञात करें​

Answer 1

Answer:

Rs.420

Step-by-step explanation:

Selling Price = Rs.360

Loss = 10%

=> (100-10)% of C.P. = 360

=> 90% of C.P. = 360

=> 90/100 × C.P. = 360

=> C.P. = Rs.400

Profit = 5%

Hence, new selling price = 105% of 400 = 105/100 × 400 = Rs.420

Answer 2

Step-by-step explanation:

$c.p = (\frac{100}{100 - 10} ) \times 360 = \frac{100}{90} \times 360 = 400$

$s.p \: when \: profit\% = 5\% \\ = (\frac{100 + 5}{100} ) \times 400 = \frac{105}{100} \times 400 = 420$
