Question

A farmer spends $752$ pounds in buying horses and cows. If each horse costs $37$ pounds and each cow $23$ pounds, how many of each does he buy?

• A. $11$ horses and $15$ cows
• B. $7$ horses and $20$ cows
• C. $16$ horses and $4$ cows
• D. $13$ horses and $17$ cows

Answer 1

The correct option is A $11$ horses and $15$ cows

The cost of horse is $37$ pounds

The cost of cow is $23$ pounds

Let the number of horses be $x$ and the number of cows be $y$

We have $37x+23y=752$

So $x=11$ and $y=15$ satisfies the above condition

So the farmer buys $11$ horses and $15$ cows

Therefore the correct option is $A$
