Problem Analysis

The problem states that in a certain country, there are no coins, only banknotes are used. The seller needs to count out 70 bolivars in change to the first buyer, 80 bolivars to the second buyer, and 40 bolivars to the third buyer. The seller has three bundles of banknotes, each containing 100 banknotes of 1 bolivar each. The seller can count out one banknote per second. We need to determine the minimum amount of time it takes for the seller to count out the change to all the buyers.

Solution

To find the minimum time it takes for the seller to count out the change to all the buyers, we need to calculate the total number of banknotes the seller needs to count.

The seller needs to count out 70 bolivars to the first buyer, 80 bolivars to the second buyer, and 40 bolivars to the third buyer. This adds up to a total of 190 bolivars.

Since each banknote is worth 1 bolivar, the seller needs to count out 190 banknotes.

The seller can count out one banknote per second, so the minimum time it takes for the seller to count out the change to all the buyers is 190 seconds.

Therefore, the seller can count out the change to all the buyers in a minimum of 190 seconds.

Conclusion

In conclusion, the seller can count out the change to all the buyers in a minimum of 190 seconds.
