Shortcut Trick

When the Selling Price (SP) is the same for two articles, the ratio of their Cost Prices (CP) is inversely proportional to their Selling Price percentages (100 ± Profit/Loss%).

SP percentage for A = 100 + 10 = 110%

SP percentage for B = 100 − 25 = 75%

Ratio of CP_A : CP_B = 75 : 110 = 15 : 22

∴ The correct answer is 15 : 22.

Alternate Method

Given:

Selling Price (SP) of watch A and watch B = ₹5,400

Profit percentage for A = 10%

Loss percentage for B = 25%

Formula Used:

Cost Price (CP) = [SP × 100] ÷ (100 ± Profit/Loss %)

Calculations:

⇒ Cost Price of watch A (CP_A) = (5400 × 100) ÷ (100 + 10)

⇒ CP_A = 540000 ÷ 110 = 54000 ÷ 11

⇒ Cost Price of watch B (CP_B) = (5400 × 100) ÷ (100 − 25)

⇒ CP_B = 540000 ÷ 75 = 7200

⇒ Ratio of CP_A to CP_B = (54000 ÷ 11) : 7200

⇒ Ratio = (540 ÷ 11) : 72

⇒ Ratio = 540 : (72 × 11)

⇒ Ratio = 540 : 792

⇒ Dividing both sides by 36: 15 : 22

∴ The correct answer is 15 : 22.

Cost Price and Selling Price Relation

If an article is sold at a profit of P%, then SP = CP × (100 + P)/100. If sold at a loss of L%, then SP = CP × (100 − L)/100.

Constant Selling Price Rule

When the Selling Price of two items is the same, the ratio of their Cost Prices is the inverse ratio of their respective multiplying factors (1 + g/100) or (1 − l/100).

Profit and Loss Percentage

Profit% = (Profit ÷ CP) × 100 and Loss% = (Loss ÷ CP) × 100. Both are always calculated on the Cost Price unless stated otherwise.

Given:

The sum of three consecutive even numbers is 126.

Formula:

The sum of n consecutive even numbers can be found using the formula: n/2 × (first number + last number)

Calculation:

The sum of three consecutive even numbers is 126, which can be represented as x + (x + 2) + (x + 4) = 126, where x is the smallest of the three numbers.

To find the value of x, we can simplify the equation and solve for x:

3x + 6 = 126

3x = 120

x = 40

Therefore, the smallest of the three numbers is 40, the largest is 40 + 4 = 44, and the product of the smallest and the largest numbers is 40 × 44 = 1760.
