Answer 1

Answer:

Answer:

Let the cost price at which Raju purchased be 'x'.

It is given that he sold to Amit for a profit of 8%.

\implies \boxed{x + \dfrac{8}{100} \times x = \text{Cost Price for Amit}}⟹

x+

100

8

×x=Cost Price for Amit

⇒ 1.08x = Cost Price for Amit ...(i)

Now Amit spends Rs. 54 on repairing and sells it to Nikhil for Rs. 1134 gaining no profit or loss. Therefore this means that, Amit sells it at the same cost with which he bought just by adding the additional repair expense.

⇒ Cost Price for Amit = Selling price of Nikhil - Repair Charges

⇒ Cost Price for Amit = 1134 - 54

⇒ Cost Price for Amit = Rs. 1080 ...(ii)

We know that Cost price of Amit = 1.08x (from (i))

Equating (i) and (ii) we get:

⇒ 1.08x = 1080

⇒ x = (1080/1.08)

⇒ x = 1000

Hence the cost price for which Raju purchased the cycle was Rs. 1000
