Raju sold an article to Ravi at 10% gain. Ravi sold the article to Ramu at a loss of 10%. If Ramu paid Rs. 1,485 to Ravi, Find the selling price of Raju to Ravi.

Correct option is C

Given:
Raju sold the article to Ravi at a gain of 10%.
Ravi sold the article to Ramu at a loss of 10%
Selling price of Ravi to Ramu = Rs. 1,485
Solution:
let Raju bought an article = 100x
Raj sold it at 10% gain, So
Ravi bought it at the price = 100x+ 10% of 100x = 100x+ 10x = 110x
Ravi sold it at 10% loss, so
Ramu bought it at the price = 110x-10% of 110 = 99x
ATQ
99x = Rs. 1485
x= Rs. 15
So, Raju bought an article = 100x = 100 × 15 = Rs. 1500

Raju sold article to Ravi = $$1500 \times \frac{110}{100} = Rs. \ 1650$$​​
Alternate Method:

99 unit = 1485
1 unit = 15
So, Selling Price of Raju to Ravi = 110 unit = 110 × 15 = Rs. 1650
