* 80 per kg, some oranges at the rate of
* 40 per kg whose quantity is equal to
the square of the apple quantity. Along
that he sells 10 kg pomegranate at the
rate of 120rs per kg
(i) Write an equation of the total cost of the
quantity.​

Answer 1

Answer:

cost of orange +cost of apple +cost of pomogreneatr

Answer 2

GIVEN :

cost of apples = 80 per kg

no of apples = x

Cost of x kg of apples = 80 × x = 80x ___ 1

cost of oranges = 40 per kg

no of oranges = x² ( square of the apple quantity )

total cost of oranges = 40 × x² = 40x²

cost of pomegranate = 120 per kg

no of pomegranate = 10 kg

total cost of pomegranate = 120 × 10 = 1200

equation:

total cost of the quantity = cost of apples + cost of oranges + cost of pomegranate

= 80x + 40x² + 1200
