The Naga Jolokia pepper measures 854 thousand Scoville units.

Work Step by Step

We know that the habanero pepper is 577 thousand Scoville units, and that the Naga Jolokia pepper is 48% hotter than the habanero. This is mathematically represented by the equation: $\frac{x - 577}{577}$ = 0.48, where x is equal to the Scoville units of the Naga Jolokia pepper. To solve for x, multiply 0.48 $\times$ 577, then add 577, and you get 853.96. The problem says to round to the nearest thousand, so the answer comes out to be 854 thousand Scoville units.
