Hi
Distribution: normal with µ = 616 and σ = 13
Using TI or similarly an inexpensive calculator like an Casio fx-115 ES plus

The heaviest 15% of fruits weigh more than how many grams?

z+=blue+%28x+-+mu%29%2Fblue%28sigma%29 OR blue%28sigma%29%2Az+%2B+mu=blue+%28x%29
invNOrm(.85) = 1.0364
(1.0364)*13 + 616 = 629.4732gm  
The heaviest 15% of fruits weigh more than  629.4732gm 
Wish You the Best in your Studies.
