Tips & Tricks
Given:
Marked Price = Rs. 2000
1st Discount % = 30%
2nd discount % = 20%
3rd discount % = 10%
Calculation:
1st discount $=2000\times \left(30/100\right)$
= Rs. 600
∴ Price of cooker after 1st discount $=\mathit{R}\mathit{s}.2000-\mathit{R}\mathit{s}.600$
= Rs. 1400
2nd discount $=1400\times \left(20/100\right)$
= Rs. 280
∴ Price of cooker after 2nd discount $=\mathit{R}\mathit{s}.1400-\mathit{R}\mathit{s}.280$
$=\mathit{R}\mathit{s}.1120$
3rd Discount $=1120\times \left(10/100\right)$
$=\mathit{R}\mathit{s}.112$
∴ Price of cooker after 3rd discount $=\mathit{R}\mathit{s}.1120-\mathit{R}\mathit{s}.112$
$=\mathit{R}\mathit{s}.1008$
∴ Selling Price of cooker after all 3 discounts = Rs. 1008
Short Method:
Selling Price after all the discount
= Rs. 1008
