Question

a man bought 500 m of electronic wire at 50paise/m.he sold 50% of it at a profit of 5%.At what percent should he sell the remainder so as to gain 10% on the whole transaction.​

Answer 1

Answer:

m = 500

cost = 500 × .5 = ₹250

sold = 50% = 250 m

profit = 5%

= 125 × 5/100 = 6.25

he got ₹6.25 as profit

he sold it at 125 + 6.25 = 131.25

250 × 10/100 = 25

10 % of 250 is 25

so 250 + 25 = 275

275 - 131.25 = 141.75

141.75 = 125 + 16.5

16.5 = 125 × 13.4/100

so he have to sell the remaining wire at

a profit of 13.4% to gain total 10% of ₹250
