Question

A man makes profit of 15% by selling an article for Rs 250 .At what rate should he sell it to make a profit of 38%?​

Answer 1

Answer:

Step-by-step explanation:

→ original selling price = ₹250

→ profit= 15%

→ let the cost price of article be ₹ x

→ x + 15% of x = 250

→ 1.15x = 250 => 115x ÷ 100 = 250

→ 115x = 25000 => x = 25000 ÷ 115

→ x = 5000/ 23

→ cost price of article = ₹5000/ 23

→ required profit = 38%

= 38% of 5000/ 23 = 0.38 × 5000/ 23

= 1900/ 23

→ required selling price to gain 38%

= cost price + required profit

= (5000/ 23) + (1900/ 23)

= 6900/ 23 = ₹300

→ Required selling price = ₹300

Answer 2

sp=rs250

profit=15%

CP=sp(1+r/100)ofcp

=250(1+15/100)ofcp

250=115/100 of CP

CP=250*100/115 =rs5000/23

again

profit=38%

new sp=(1+38/100)of 5000/23

=138/100*5000/23

=RS 138(ANSWER)
