Solution

Selling Price = 14,400
Let the M.P. be 100.
First discount =10% =10100×100= 10
S.P. after the first discount =10010= 90
Second discount =20% =20100×90= 18
Selling Price after the second discount =9018= 72
If S.P. is 72, then M.P. is 100.
When S.P. is 14,400,
M.P. =14400×10072= 20,000
M.P. = 20,000.
