1.	Jaspreet bought a goat and a cow at total price of Rs 10320. He sells the goat at the profit of 25% and cow at a loss of 18%. He neither gained nor lost any money in whole transaction. If he sells goat at 25% profit then at what price he should sell the cow to gain a total profit of 15% in whole transaction?1). Rs. 64682). Rs. 63563). Rs. 54004). Rs. 3852
Answer» Let us ASSUME the cost price of goat and cow is Rs. X and Rs. Y respectively. Total cost price = X + Y = 10320----(1) We know that, SELLING price of goat = X + (25% of X) = 1.25X Selling price of cow = Y – (18% of Y) = 0.82Y Since he NEITHER gained nor LOST any money, ∴ Total selling price of goat and cow = total cost price = 10320 ⇒ 1.25X + 0.82Y = 10320----(2) Solving EQUATION (1) and (2), we get: X = 4320; Y = 6000 Selling price of goat after 25% profit = 1.25X = 1.25 × 4320 = 5400 To get a total profit of 15% total selling price should be, ⇒ Total Selling price = 10320 × 1.15 = 11868 ∴ Selling price of cow = 11868 – 5400 = Rs. 6468

Answer»

Let us ASSUME the cost price of goat and cow is Rs. X and Rs. Y respectively.

Total cost price = X + Y = 10320----(1)

We know that,

SELLING price of goat = X + (25% of X) = 1.25X

Selling price of cow = Y – (18% of Y) = 0.82Y

Since he NEITHER gained nor LOST any money,

∴ Total selling price of goat and cow = total cost price = 10320

⇒ 1.25X + 0.82Y = 10320----(2)

Solving EQUATION (1) and (2), we get:

X = 4320; Y = 6000

Selling price of goat after 25% profit = 1.25X = 1.25 × 4320 = 5400

To get a total profit of 15% total selling price should be,

⇒ Total Selling price = 10320 × 1.15 = 11868

∴ Selling price of cow = 11868 – 5400 = Rs. 6468
