1.	Anuj bought 18 watches of same price and sold them at Rs. 250 each. He made a profit equal to the cost price of 2 watches. The cost price of each watch is?1. Rs. 2252. Rs. 2003. Rs. 2504. Rs. 220
Answer» Correct Answer - Option 1 : Rs. 225 Given: Total number of watches = 18 SP of each watch = Rs. 250 Profit = CP of 2 watch Concept: Consider the CP of each watch be 'y'. Write the CP of total watches, then proceed to calculate the answer. Formula used: Profit = Selling Price - Cost price Calculation: Let, the CP of each watch = y CP of 18 watches = 18y SP of 1 watch = Rs. 250 ⇒ SP of 18 watches = 18 × 250 = Rs. 4500 ∵ Profit = Selling Price - Cost price ⇒ 2y = 4500 – 18y ⇒ 2y + 18y = 4500 ⇒ 20y = 4500 ⇒ y = 4500/20 ⇒ y = Rs. 225 ∴ The cost price of each watch is Rs. 225

Answer» Correct Answer - Option 1 : Rs. 225

Given:

Total number of watches = 18

SP of each watch = Rs. 250

Profit = CP of 2 watch

Concept:

Consider the CP of each watch be 'y'. Write the CP of total watches, then proceed to calculate the answer.

Formula used:

Profit = Selling Price - Cost price

Calculation:

Let, the CP of each watch = y

CP of 18 watches = 18y

SP of 1 watch = Rs. 250

⇒ SP of 18 watches = 18 × 250 = Rs. 4500

∵ Profit = Selling Price - Cost price

⇒ 2y = 4500 – 18y

⇒ 2y + 18y = 4500

⇒ 20y = 4500

⇒ y = 4500/20

⇒ y = Rs. 225

∴ The cost price of each watch is Rs. 225
