Question

A tv is sold for ra 10350 with 15% profit. Find the cp of tv

Answer 1

CP=SP*100÷100+P

so,

CP=10350*100÷100+15

CP=9000

Answer 2

solution

Explanation:

Let.the cp of TV be RS X

now,CP=SP-profit

or, CP=SP-profit% of Cp (as profit amount =profit % of Cp)

or, x=Rs 10350-15÷100× X

or, x= Rs 10350 _ 3X ÷20

or, x+3x ÷20 =Rs 10350

or, 23x ÷20 = Rs 10350

or, x = 10350×20 divided by 23

Therefore X =Rs 9000
