Answer 1

Answer:

first we will know the price B bought the scooter.

1040*20/100=208

1040+208=1248

1248 is the price B bought the scooter.

1248*30/100=374.4 is the ans.

Answer 2

Answer:

2) 300

Step-by-step explanation:

C.P ( C ) = S.P ( B ) = 1040

L% = L / C.P × 100

20 = C.P – S.P / C.P × 100

20 / 100 = 1 – 1040 / C.P

1040 / C.P = 1 – 20 / 100 = 80 / 100

C.P = 100 × 1040 / 80

C.P ( B ) = 1300

C.P ( B ) = S.P ( A ) = 1300

P% = 30

C.P ( A ) = S.P × 100 / 100 + P%

= 1300 × 100 / 100 + 30

= 1300 × 100 / 130 = 1000

C.P ( A ) = 1000

S.P ( A ) = 1300

Profit = 300
