Question

find the sp when the cp is rs 3080 and gain percent is 10 %

Answer 1

Answer:

shopkeeper sells two mobiles for Rs. 3,080 each

On one, he gets 12% profit and on the other, 12% loss

Concept:/Formula:

If CP is Rs. x and SP is y, then

Profit = (y – x)

Loss = (x – y)

If profit percentage be x% and loss percentage be y%, then

SP = CP × (100 + x)/100

SP = CP × (100 – x)/100

Calculation:

Total selling price of both mobiles = Rs. 3080 × 2 = Rs. 6160

Cost price of first mobile = Rs. 3080 × 100/112 = Rs. 2750

Cost price of second mobile = Rs. 3080 × 100/88 = Rs. 3500

Total cost price of both mobiles = 2750 + 3500 = Rs. 6250

⇒ Loss = 6250 – 6160 = 90

⇒ Loss % = 90/6250 × 100

∴ Loss% = 1.44% or %
