We know that,

Television costs four times as much as the radio

Means

4x + x = 15000

5x = 15000

x = 15000 / 5

x = 3000

x = ₹3000

Cost of radio is ₹3000

We know that,

Television costs four times as much as the radio

Therefore,

Cost of television set = x × 4x

Cost of television set = 4x

Cost of television set = 4 × 3000

Cost of television set = 12000

Cost of television set = ₹12000
