Question

computer set was sold at a profit of 7% if it had been sold at a profit of 10% the profit could have been Rs 780 more what is its CP​

Answer 1

Answer:

26000

Step-by-step explanation:

let the cp be= rs x

profit=7%, i.e , r=20,

$1 + \frac{r}{100} \times cp$

ans=

$\frac{107x}{100}$

profit=10%

$sp = (1 + \frac{r}{100} ) \times cp$

$ans = \frac{110x}{100}$

$\frac{107x}{100} + 780 = \frac{110x}{100}$

final answer =26000

Answer 2

Step-by-step explanation:

let the cp be= rs x

profit=7%, i.e , r=20,

1 + \frac{r}{100} \times cp1+100r×cp

\frac{107x}{100}100107x

profit=10 percent

sp = (1 + \frac{r}{100} ) \times cpsp=(1+100r)×cp

ans = \frac{110x}{100}ans=100110x

\frac{107x}{100} + 780 = \frac{110x}{100}100107x+780=100110x

100110x

\frac{107x}{100} + 780 = \frac{110x}{100}100107x+780=100110x

final answer =26000
