Answer 1

Step-by-step explanation:

S.P=11/2(Discount)

Profit=S.P-C.P

D=11/2(D)-C.P

C.P=9D/2

240(2)/9=D

Now S.P=11/2(480/9)=1760/6=880/3=293.3/-

Answer 2

Correct Question

If the SP of the book is 11/2 times the discount offered and the discount % is equal to the profit %it is given that the discount is 240rs find the cp of the book.

The CP is Rs. 1116.92

Given

• The sale price is 11/2 times the discount offered
• Discount% = Profit%
• Discount = Rs.240

To Find

Cost Price

Solution

Sale Price = 11/2 times the discount offered

Therefore,

Sale Price = 11/2 * 240

= Rs. 1320

Discount % = (Discount/Selling Price) * 100

= (240/1320)*100

= $18\frac{2}{11} %$%

Therefore Profit Percent = $18\frac{2}{11}$%

Profit Percent = (Profit/Cost Price)*100

Profit = Sale Price - Cost Price

Let the Cost Price be Rs. x

Therefore,

100(1320- x)/x = $18\frac{2}{11}$

or, (1320 -x)/x=200/1100

or, 2x= 14520-11x

or, 13x = 14520

or, x = 1116.92

Hence,

The cost Price is Rs. 1116.92
