All grads: 800
Half are women: 400 W

We've already split the population in half, so

W who WILL own a business = 15 percent: (0.15*400) = 60

W who will NOT own a business: (400 - 60) = 340

Or: (1/2 grads) * (percent not B) * (all grads)
(0.5 * 0.85 * 800)= 340

Answer D

Given, Total no of graduates=800,
No of Women graduates=\(\frac{1}{2}*800\)=400
No of women graduates who will set up their own business=15% of 400=60
No of women graduates who will NOT set up their own business=400-60=340

Ans. (D)

Poor quality question for 2 reasons..
1) the choices are in no order. Any reliable source on GMAT would place the choices in order.
2) 15% of all graduates means 15% of total so 15% of 800 = 120. but breakdown of these 120 is NOT given.

so we know 400 are male graduates and 400 are female graduates. Apart from this, we know 120 start their own business.
Data insufficient to answer - "How many women graduates will NOT set up their own business"
