Solution:

C.P. of article B = Rs. x
C.P. of article A
= Rs. (x + 200)
According to the question

{x×25}/{100}

{10}/{100}

(x + 200)
= (2x + 200) ×

4/{100}

⇒

x/4-x/{10}

- 20 =

{8x+800}/{100}

⇒

x/4-x/{10} - {8x}/{100}

= 20 + 8 = 28
⇒

{25x-10x-8x}/{100}

= 28
⇒

{7x}/{100}

= 28 ⇒ x =

{28 × 100}/7

= Rs. 400
