At one point, she believed GMAT wasn’t for her. After scoring 595, self-doubt crept in and she questioned her potential. But instead of quitting, she made the right strategic changes. The result? A remarkable comeback to 695. Check out how Saakshi did it.

Cookies which have both nuts and chocolate chips = 135
Let fewest possible number of cookies with both chocolate chips and nuts that would need to be added to that
batch so that cookies with both nuts and chocolate chips represented more than 3/5 of all the cookies in the batch = x
(135+x)/(500+x) = 6/10
=>1350 + 10x = 3000 + 6x
=> 4x = 1650
=> x = 412.5
Therefore x = 413

Thanks in advance for any reply !!
Please help me in understanding this question correctly!!
Since the question asks for "fewest possible cookies", shouldn't it be that we consider maximum overlap between 320 and 230 i.e. 230 rather 135 and then try to find the "fewest possible number of cookies with both chocolate chips and nuts that would need to be added to that batch so that cookies with both nuts and chocolate chips represented more than 3/5 of all the cookies in the batch"
Considering, 230 as the maximum overlap to find fewest possible .... 3/5 of all the cookies in the batch, as stated above in the solution by Skywalker18. The equation would become as below:
(230+x)/(500+x)=6/10
x=175
why is this not correct ? or why is it wrong to consider 230 already having both nuts and choco chips rather than 135?
