Question

plz tell the answer of Q 7, 8, 9 ​

Answer 1

Step-by-step explanation:

(7) Let the required amount of money is x

According to the question ,

25% of x = 350

$= > \frac{25}{100} x = 350$

$= > \frac{x}{4} = 350$

$= > x = 350 \times 4$

=> x = 1400.

Hence the answer is 1400 Rupees.

$(8) \: sp = cp(1 - loss\%)$

$= 537000(1 - 18\%)$

$= 537000( \frac{100 - 18}{100} )$

$= 537000 \times \frac{82}{100}$

$= 5370 \times 82$

$= 440340$

So the selling price is 4,40,340 rupees.

(9) Loss = 14 -12 = 2 pens

=> Loss% =

$\frac{2 \times 100}{12} \%$

$= 16 \frac{2}{3} \%$

$= \frac{50}{3} \%$
