Answer 1

A. 260

Step-by-step explanation

Step 1

Let

`\begin{gathered} green\text{ jolos,one-headed jolo=170} \\ \text{Purple ,two-headed jolos=284} \\ one\text{ headed jolos=430} \end{gathered}`

as we can see

the total of green-one headed jolo is 170

and the total for one headed jolo is =430

so, the one-headed in counted twice

`\begin{gathered} total\text{ of gr}en\text{ jolos= }430-170 \\ total\text{ of gr}en\text{ jolos= }260 \end{gathered}`

so, the answer is

A.260
