Answer 2

The selling price is Rs 12000 if discount is 22 %

Solution:

At 9% discount the selling price of a washing machine is  Rs-14000

Let the marked price be 100x

Discount = 9 %

Therefore,

selling price = marked price - discount in marked price

$selling price = 100x - 9 % of 100x\\\\selling\ price = 100x - \frac{9}{100} \times 100x\\\\selling\ price = 100x - 9x\\\\selling\ price = 91x$

From given, selling price = 14000

91x = 14000

$x = \frac{14000}{91}\\\\x = \frac{2000}{13}$

what is the selling price if the discount is 22%?​

selling price = marked price - 22 % on marked price

$selling\ price = 100x - \frac{22}{100} \times 100x \\\\selling\ price = 100x - 22x = 78x$

Substitute for x

$selling\ price = 78 \times \frac{2000}{13}\\\\selling\ price =12000$

Thus selling price is Rs 12000 if discount is 22 %
