Answer 1

Answer:

Option D.

Step-by-step explanation:

Let initial price of music system = 1000rs

Therefore initial price of TV =  3000rs

Price of TV when increased by 10% =  3300rs

Price of Music Sys. when inc. by 18% = 1180rs

New Total= (3300x8) + (1180x5) = 32300rs

Old Total= (3000x8) + (1000x5) = 29000rs

Profit % =330000/29000 = 11.37 ~ 12% [Formula= (Profit/CI)x100 ]
