Show answer & explanation

Correct answer: B

Explanation

The correct answer is option 2 i.e. 640.

Let the CP of  an article for A = 100x

SP of an article For A = CP of an article for B = 100x × 125% = 125x

SP of an article for C = CP of an article for A =  125x × 115% = 143.75x.

Profit made by B = 143.75x - 125x = 18.75x.

xProfit made by A = 125x - 100x= 25x

Difference of their profits = 25x - 18.75x = 40

6.25x = 40

x = 6.4.

Cost price pf an article = 100x = 100 × 6.4 = 640.
