Question

the cost of groundnuts vary directly as its weight, if the cost of 2.5 kg groundnut is 275 what is the cost of 1 quintal of groundnut?
koi hai?​

Answer 1

Answer:

$\Large\bold\red{Yup}$

$\huge \dag \sf{Answer \: is}$

Let the cost of groundnuts be x and weight of groundnuts be y. It is given that x varies directly as y \ x D y or x = kyIt is given that when x = 450 then y = 5, hence we will find k.

x = ky \ 450 = 5k \ k = 90 (constant of variation)

equation of variation is x = 90y.

if y = 100, x = 90 u 100 = 9000

cost of 1 quintal groundnut is ` 9000.

Answer 2

Let the cost of groundnuts be x and weight of groundnuts be y. It is given that x varies directly as y \ x D y or x = kyIt is given that when x = 450 then y = 5, hence we will find k.

x = ky \ 450 = 5k \ k = 90 (constant of variation)

equation of variation is x = 90y.

if y = 100, x = 90 u 100 = 9000

cost of 1 quintal groundnut is ` 9000.
