sanjay sold an article at a loss of 25 percent if the selling price had been increased by rs 175.there would have been gain of 1
vagabundo [1.1K]

Answer:

The cost price is Rs.500

Explanation:

<em>I'll approach this question by taking the statements in the question, one after the other</em>

Let the cost price be represented by CP

From the first statement:

Sanjay made a loss of 25%

The selling price (SP) is as follows;

SP = CP - 25\% * CP

Convert percent to fraction

SP =CP -  \frac{25}{100} * CP

Get decimal equivalent

SP = CP-0.25 * CP

SP = CP - 0.25CP

SP = 0.75CP

From the second statement:

If the selling price was increased by 175%, Sanjay would make a profit of 10%

Hence; The new selling price is

SP = 0.75CP + 175

The selling price can also be calculated from the profit

SP = CP + 10\% * CP

Convert percent to fraction

SP = CP + \frac{10}{100} * CP

Get decimal equivalent

SP = CP + 0.10 * CP

SP = CP + 0.10 CP

SP = 1.10 CP

Equate both values of SP (SP = SP)

1.10CP = 0.75CP + 175

Collect Like Terms

1.10CP - 0.75CP = 175

0.35CP = 1.75

Divide both sides by 0.35

CP = \frac{175}{0.35}

CP = 500

<em>Hence, the cost price is Rs.500</em>
