Please Give me the varified answer, Otherwise I will report you....​

Answer 1

Answer:

cp=540

Step-by-step explanation:

sp = 594

profit % = 10%

profit% = (sp-cp / cp) × 100

10 = (594 -cp/ cp) × 100

10 cp / 100 = 594-cp

10 cp / 100 +cp = 594

110 cp/ 100 = 594

cp/10=54

cp=540

answer

Answer 2

Answer:

Original cost of the wristwatch = Rs 540

Step-by-step explanation:

Given: Romy sold a wristwatch for Rs 594.

i.e., SP = Rs 594

Gained a profit of 10%

Let us suppose that original cost of the wristwatch be x.

Formula: SP = CP + profit% of CP

594 = x + 10% of x

→ x + 0.1x = 594 [% = 0.01]

→ 1.1x = 594

→ x = 540

∴ CP of that wristwatch = Rs 540

Some abbreviations are:

CP = Cost price

SP = Selling price
