Question

A farmer bought a number of pigs for $230. However, 6 of them died before he could sell the rest at a profit of 6 per pig. His total profit was $42. How many pigs did he originally buy?

Answer 1

Bob,

 

Since his total profit was $42 and his profit per pig was $6, the number of pigs sold was $42÷ ($6 per pig) = 7 pigs sold.

 

We are also told that 6 pigs died, so the total number of pigs bought was 7 + 6 =13
