Answer 10

sorry, i was away

and please be nice. it's not nice blaming and shaming other person who tried to help you. One should understand why they chose helper's answer first, before you follow them.

Quantity of 67% - let this be 'x'
Quantity of 42% will be 42-x based from the question

so you'll have
0.67x + 0.46 ( 42-x) = 0.55*42

simplify this and solve for x
