(1) 25% of the people who had Veg also had Non–Veg.

(2) 20% of the people who had at least one of the two variants had both the variants.

1) the information about those who took both tells us nothing about the breakdown of the 60% who took only one of two (it could be anywhere between 0% and 60% only veg). . Insufficient!
2) once again, this only tells the size of the "both" group, not the "only veg". insufficient!

Combined - both statements describe the "both" group in different ways, so we know that 20% of the total equals 25% of the veg group. If we call the only veg group y, this gives us the following equation:
y/4=(60 + y/4)/5
5y/4=60+y/4
4y/4=60
y=60
sufficient!
