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:

I'll approach this question by taking the statements in the question, one after the other

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

$CP = \frac{175}{0.35}$

$CP = 500$

Hence, the cost price is Rs.500

How did Native Americans used their geography to their advantage.

True [87]

Answer:

The Great Plains had rivers which allowed various Native American tribes to camp along these rivers while they were following the buffalo. So again, the geography of the area provided this availability of food and places to stay and feed and water their horses.
