Home furniture brand Blu Dot blew up on CTV with help from Roku Ads Manager. Here’s how:

After a test campaign reached 211,000 households and achieved 1,010% ROAS, the brand went all in to promote its annual sales event. It removed age and income constraints to expand reach and shifted budget to custom audiences and retargeting, where intent was strongest.

The results speak for themselves. As Blu Dot increased their investment by 10x, ROAS jumped to 2,308% and more page-view conversions surpassed 50,000.

“For CTV campaigns, Roku has been a top performer,” said Claire Folkestad, Paid Media Strategist, Blu Dot. “Comping to our other platforms, we have seen really strong ROAS… and highly efficient CPMs, lower than any other CTV partner we've worked with.”

Using Roku Ads Manager, the campaign moved from a pilot to a permanent performance engine for the brand.

We have 5 persons and 7 different vehicles:

Persons: Lokesh, Subash, Mahesh, Rupesh, Ramesh
Vehicles: Car, Bike, Scooty, Jeep, Van, Bus, Auto

No vehicle can be driven by more than one person.

We are directly told:

Thus, these three account for 3 vehicles.

There are 7 vehicles in total, so the remaining:

7 − 3 = 4 vehicles

must be divided between Rupesh and Ramesh.

Since nobody can drive more than 2 vehicles:

So:

Rupesh does not drive:

Therefore, Rupesh can drive only:

Car, Bike, Van

But Rupesh must drive exactly 2 vehicles.

The clue says:

Therefore, the same person cannot have both Car and Bike.

So Rupesh cannot have:

❌ Car + Bike

Hence Rupesh's two vehicles must be either:

Car + Van

or

Bike + Van

Therefore:

Ramesh does not drive:

So Ramesh can drive only:

Jeep, Van, Bus

Ramesh needs exactly 2 vehicles.

But Van is already driven by Rupesh.

Since no two persons can drive the same vehicle:

This is completely fixed.

Lokesh drives either:

Jeep or Scooty

and drives only one vehicle.

But Jeep is already driven by Ramesh.

Therefore:

So far:

The remaining vehicles are:

Car, Bike and Auto

Mahesh drives only one vehicle and cannot drive:

So among the remaining vehicles, Mahesh must drive:

Therefore, Subash must drive:

There are two possible cases.

Thus, only Car and Bike interchange between Mahesh and Rupesh.

It could be:

Therefore:

Answer: D. Cannot be determined ✅

Rupesh has either:

So Van is common in both cases.

Answer: C. Van ✅

Ramesh definitely drives:

Jeep + Bus

Therefore:

Answer: D. Jeep, Bus ✅

Mahesh can drive:

It cannot be uniquely determined.

Answer: D. Cannot be determined ✅
