A person sold an article at a profit of 15% if he sold it for Rs 81 less , his loss would have been 12% find the cost price of t

Misha Larkins [42]

Answer:

let cp be x

sp= 115x/100 ---(when 15%gain)

sp = 88x/100------(when 12% loss

according to question

115x/100 - 88x/100 = 81

or, (115x-88x)= 8100

or, 27x = 8100

or, x= 8100/27

x = 300

hence cp is RS 300

A square storage unit has a volume of 607.5 ft3. The height of the unit is 7.5 ft. What are the length and width of the storage

Eduardwww [97]

Answer:

9ft

Step-by-step explanation:

The base area of the storage is its volume divided by height

$A = \frac{V}{h} = \frac{607.5}{7.5} = 81 ft^2$

Since this base is a square, its length and width is of equal length, which is

$\sqrt{A} = \sqrt{81} = 9ft$
