A shopkeeper bought an electric fan for Rs 2,000 and fixed its price 20% above the cost price. If he/she then gives 15% discount, how much should a customer pay for it with 15% VAT? ​

2040

Step-by-step explanation:

2000+ 20%=2400-15%=2040

pls mark brainiest

Step-by-step explanation:

100%= Rs2000

1%=Rs 20

120%= Rs2400

Cost is 2400 Rs

100%= 2400

1%= 24

(100-15=85)

85%= 2040

With discount it is Rs2040

Then with an extra 15% VAT

100%= 2040

1%= 20.4

115%= 2346

I think the answer is Rs2346

hello from mrbilldoesmath!

answer:   (7x + 6y) ( 49x^2 - 42xy + 36y^2)

discussion:

in general, the factorization of a^3 + b^3 is

a^3 + b^ 3 = (a + b) ( a^2 - ab + b^2)

in our case note that 343 = 7^3 and 216 = 6^3 so the equation becomes:

343x^3 + 216y^3 = (7x)^3 + (6y)^3

if you think of a (above) as 7x and b as 6y the factorization becomes

343x^3 + 216y^3 =

((7x + 6y) (   (7x)^2 - 7x*6y + (6y)^2)   =

(7x + 6y) ( 49x^2 - 42xy + 36y^2)

(a + b) (a^2 - a b + b^2)
