vas sells an article to radha and a profit of 20% radha sells it to man at a profit of 4%. what dos it cost vas if mans has paid rs624.

ans rs 500

 Let CP to Vas be x

SP = Profit = 20% = CP + Profit = x + 20x/100 = 6x / 5

Now CP to Radha = 6x / 5

SP = CP + Profit

Profit = 4%

SP = 6x / 5 + 4x / 100

SP = 120x + 4x / 100

SP = 124x / 100

CP to man = 124x / 100

It is given that = 124x / 100 = 624

x = 624 ⁵  * 100 /124

x = 500

Please give me thumbs up
