we have to choose one from each set. 1 from 7 nouns and 1 from 5 verbs and 1 from 2 adjectives.
then we have 2 arrange 3 different set in 3! ways.
so,
7c1*5c1*2c1*3!=420

(7C1 * 5C1 *2C1 ) 3!
7C1 for chosing 1 from 7
5C1 for choosing 1 from 5
2C1 for choosing 1 from 2
now these 3 words can arrange in 3!= 6
so total 7*5*2*6=420
