I need to know if a 150cc engine of motor bike will pull the total weight of the buggy having 280kg

Geared properly it would, but it's not going to be very powerful at all. I would guess that sugar sand could be a real problem. IMHO Go bigger.

How about a 200cc ktm Duke engine?

What type of terrain will you be riding on? Either of those 2 engines will get you around on firm ground, if geared properly.

But at 280KG/617LBS I don't think either will be very good on soft terrain, like sand or mud.

I think those Chinese 150cc buggies weigh about 180KG/400LBS. They will barely go through sugar sand, but they're only about 10HP, and use a CVT type transmission. I'm guessing your Duke should have a little more than double that 24hp? and the option to shift gears manually.

A TRX 450R weighs 176KG/388LBS and has about 41hp. I would think you would want at least that or more. Or significantly lower the weight.

Okay, so what will be the minimum weight for an 200cc engine can carry

Depends on the type of terrain you will be riding on, and what level of performance you want. With 24hp, I personally wouldn't bother with anything over 180KG/400LBS.

The terrain will be almost a normal ground with out any road

Or it would be a paddy field probably

If the paddy field is very wet and soft, you will want the most hp to weight ratio as possible. If it's very dry and smooth, you can get away with less hp to weight ratio.

It'll be dry so 200cc engine can pull 280kg right

It wont be a rocket ship, but if geared properly, you should be able to have some fun.

That's all we need.
Won't it go at least 30km/hr?

With 24 hp it should be able to that pretty easy I would think. The secret will be in the gear ratio. The larger the rear sprocket the more power down low, but the less top speed. The smaller the rear sprocket, the less power down low, but the more top speed. Going too small will effect both top speed and low end power. The Chinese buggies do about 64KPH/40MPH but don't have much low end power at all.

I'll need power more than speed so I should choose large sprocket right

That's my preference, yes.
