Explanation:

- Let's work backward from the price Shyam paid, which is ?1,430.

- Mohan sold the suitcase to Shyam at a 40% profit.

- To find Mohan’s cost price, divide ?1,430 by 1.40 (which represents 140% due to the 40% profit).

- Mohan’s cost price = ?1,430 / 1.40 = ?1,021.43.

- Mohan also sold the suitcase at a profit, specifically a 20% profit when buying from Ram.

- To find Ram's cost price, divide Mohan's cost price by 1.20 (which represents 120% due to the 20% profit).

- Ram’s original cost price = ?1,021.43 / 1.20 = ?851.19.

- Correct Answer: Option 4 - 851.19
