Step-by-step explanation:
selling price of 1 kg oranges = rupees 80
so, selling price of 50 kg oranges :-
=》80 × 50
=》4000
now, profit = 800
so, Cost price (C.P) = selling price - profit
=》C.P = 4000 - 800
=》C.P = 3200
SO, purchasing rate per kg was
=》3200 ÷ 50 = 64
hence, purchasing rate = 64 rupees per kg
profit % =
=》
=》
=》
hence, profit % = 25%
Consider
(1) As x increases and y stays constant, z ______
(2) As y increases and x stays constant, z _____
(3) As x increases and z stays constant, y ______
Answer:
(1) As x increases and y stays constant, z increases
When y stays constant, z is directly proportional to x. So , as x increases the z also increases.
(2 ) As y increases and x stays constant, z decreases.
When x stays constant, z is inversely proportional to y. So , as y increases the z decreases.
(3) As x increases and z stays constant, y increases
(z stays constant)
So equation becomes
When z stays constant, y is directly proportional to x. So , as x increases the y also increases.
