Let c.p be x
x + x × 10%=3300
11x/10=3300
x=3000
s.p for 15% gain
=3000+3000×15%
=3000+450
=3450
x + x × 10%=3300
11x/10=3300
x=3000
s.p for 15% gain
=3000+3000×15%
=3000+450
=3450

Heya...
Here is your answer --
SP = ₹3300
Gain = 10%
CP = 100/100 + G%. ×SP
CP = 100/100+10 ×3300
CP = 100/110 ×3300
CP = 100× 30 (3300÷110)
CP = ₹3000
Gain = 15%
SP = 100+G%/100 ×CP
SP = 100+15/100 ×3000
SP = 115/100 ×3000
SP = 115×30 (3000÷100)
SP = ₹3450
Hence, he must sell the TV set for ₹3450 to gain 15%.
