Question

Find MP when :
1. SP = rs 554 , discount = 15%
2. SP = rs 1100 , discount = 12%​

Answer 1

here,

let m.p be 'x',

1. s.p=554

   dicount%=15

now,

discount amount=discount% of m.p

                             =15% ×x

                             =15/100 ×x

                             =0.15x

again,

m.p=s.p+discount amount

or,x=554+0.15x

or,x-0.15=554

or,0.85x=554

or,x=554/0.85

 x=651.76

so,  m.p=651.76

2. SP = 1100      

discount% = 12%​

now,

discount amount=discount% of m.p

                             =12% ×x

                             =12/100 ×x

                             =0.12x

again,

m.p=s.p+discount amount

or,x=1100+0.12x

or,x-0.12=1100

or,0.88x=1100

or,x=1100/0.88

 x=1250

so,  m.p=1250

Answer 2

Answer:

m.p=1250

Step-by-step explanation:

here,

let m.p be 'x',

1. s.p=554

  dicount%=15

now,

discount amount=discount% of m.p

                            =15% ×x

                            =15/100 ×x

                            =0.15x

again,

m.p=s.p+discount amount

or,x=554+0.15x

or,x-0.15=554

or,0.85x=554

or,x=554/0.85

x=651.76

so,  m.p=651.76

2. SP = 1100      

discount% = 12%​

now,

discount amount=discount% of m.p

                            =12% ×x

                            =12/100 ×x

                            =0.12x

again,

m.p=s.p+discount amount

or,x=1100+0.12x

or,x-0.12=1100

or,0.88x=1100

or,x=1100/0.88

x=1250

so,  m.p=1250
