Answer 1

Answer:

1.) rs. 10

2.) rs.1020

3.)14.28

Step-by-step explanation:

1.)Price:- Let it be x

Discount:- 10% of price

Price after discount = rs. 9 (which is price-discount)

so,

                       x-10% of x = rs. 9

                       x-10x/100 = rs. 9

                       x/1- 10x/100 = rs. 9

                       100x-10x/100 = rs.9  (the L.C.M. of 100 and 1 is 100)

                       90x/100 = rs.9

                       90x= rs.9*100

                       x = rs.900/90

                          = rs.10 ans

2.)Amount=rs.1200

Discount=15% of amount

=15% of rs. 1200

=15/100*rs.1200

=15*rs.12  (you cut the two zeros of 100 with the two zeros of 1200)

=rs.180

Amount to be paid=rs.1200

                                -rs. 180

                                 -----------

                                  rs.1020

                                 -----------

3.)Buying Price= rs.87,500

Selling Price=rs.75,000

Discount=rs.87,500-rs.75,000

              = rs.12,500

Discount%= x% of buying price= 12500

                 x/100 * 87,500 = 12500

                 x*875=12,500

                 x=12500/875

                   + 14.28 ans
