Question

hey!! please help ......
tomorrow is my exams i really need the answer.

Answer 1

${ \underline {\underline{ \sf {Here's \: the \: answer}}}}$

As per your question,

GST = 28 %

Therefore,

x + 28% of x = 2560

$\sf{x + \frac{28x}{100} = 2560}$

Simplifying it further ,

$\sf{x = \frac{256000}{128}}$

After dividing it , we get ,

$\sf{x = 2000}$

So,

In your question,

We have to find the reduction needed in the radio

= 2560 - 2000

= Rs 560

Thus,

The reduction needed in the radio is Rs.560.

Answer 2

let Reena bought the radio at Rs. X

X ×128/100= 2560
X= 2000

Now according to question
Reduction needed in the price of Radio

Marked Price (excludeGST) = 2560
Selling Price (to cancel out 28% GST) =2000

Reduction =560

Percentage of Reduction= 560/2560 ×100

= 21.875

So Reena needs
$21.875\% \: discount \:$
