Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 360.
Let's assume the price of the article A is Rs x.
So, the price of the article B = 600 - x
ATQ,
x × (120/100) + (600 - x) × (90/100) = 600 × (108/100)
(120x + 54000 - 90x)/100 = 600 × (108/100)
30x + 54000 = 64800
x = 360
The cost price of the article A = Rs 360
