Answer:

Rs. 42000

Step-by-step explanation:

Solution:

Let us consider the cost price of motorcycle for Ravish be Rs x

Loss% for Ravish = 28%

Selling price for Ravish = x – x × 28/100 = (100x – 28x)/100 = 72x/100

= Rs 18x/25

Selling price for Ravish = cost price for Vineet = Rs 18x/25

Repair cost by Vineet = Rs 1680

Total cost price of the motorcycle for Vineet = Rs18x/25 + Rs 1680

Selling price for Vineet = Rs 35910

Profit = 35910 – (18x+42000)/25

= Rs (855750 – 18x)/25

Profit % = 12.5% (Given)

By using the formula,

Gain % = (gain/cost price) × 100

=> [(855750-18x)/25] / [(18x+42000)/25] × 100 = 12.5

=> [(855750-18x)/25] × [25/(18x+42000)] = 125/1000

=> (855750-18x) / (18x+42000) = 1/8

=> By cross multiplying we get

=> 8(855750-18x) = (18x+42000)

=> 6846000 – 144x = 18x + 42000

=> 6846000 – 42000 = 18x + 144x

=> 162x = 6804000

x = 6804000/162

= 42000

∴ Cost price of motorcycle for Ravish = Rs 42000

Solution :

• Ravish sold his motorcycle to Vineet at a loss of 28% .

• Vineet spent Rs. 1680 on its repairs and sold the motorcycle to Rahul for Rs. 35910 .

• He made a profit of 12.5%

We have to find the cost price of the motorcycle ( for ravish ) .

Let us start by assuming that the cost price of the motorcycle is Rs. X

Now, ravish sold it at a look loss of 28%.

Selling price of the motorcycle for ravish -

> 72% of x

Now, this becomes the Cost price of Vineet

And He spends Rs. 1680 for repairs.

Total cost price for Vineet

> 72% of x + 1680

Now , he sold to Rahul for a profit of 12.5% .

So, 112.5% of the cost pice of Vineet is Rs. 35910

> 112.5% of ( 72% of x + 1680) = 35910

> 1125/1000 ( 72% of x + 1680) = 35910

> 72% of x + 1680 = 31920

> 72% of x = 30240

> x = Rs. 42,000

Answer - The cost pice of the motorcycle for Ravish is Rs. 42,000
