Raglan's Trout Sanctuary are trying to find out how many trout there are in a lake. They catch a sample of 95 trout and tag them. They then release these trout. The next day they catch another sample of 64 trout and find 8 of these trout had been tagged the previous day. Estimate the total number of trout in the lake.

The total number of trout in the lake is 760.

Step-by-step explanation:

We are given that Raglan's Trout Sanctuary catch a sample of 95 trout and tag them. They then release these trout.

The next day they catch another sample of 64 trout and find 8 of these trout had been tagged the previous day.

Let the total number of trout in the lake be 'N'.

Number of trout caught and tagged = 95

Number of trout caught on next day = 64

Number of trout that were tagged the previous day = 8

This situation can be represented through the following ratio;

= 760

Hence, the total number of trout in the lake is 760.

(3x-8) or (3x+8)
