Products pass successively through the hands of three traders and each of them sells
his goods at a profit of 30% of his cost price. If the last trader sold the products for
Rs.300, then how much did the first trader pay for them?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. Rs.136.55 (approx)
Let the first trader pay the amount = x Rs
According to the question
x * (13/10) * (13/10) * (13/10) = 300
x = 300000/2197 = 136.55 Rs (approx)
