Answer:
The fan = x = 400
The heater = y = 3600
Step-by-step explanation:
Let the cost price of
The fan = x
The heater = y
Aaya bought a fan and a heater for Rs 4,000.
x + y = 4000
x = 4000 - y
He sold the fan at a profit of 25%
25% × x = 0.25x
And the heater at a loss of 5%.
5% × x = 0.05y
If he gained 7% on his total outlay, at
Hence:
0.25x + 0.05y = 7% × 4,000
0.25x + 0.05y = 280
Note:
x = 4000 - y
Hence:
0.25(4000 - y) + 0.05y = 280
1000 - 0.25y + 0.05y = 280
Collect like terms
-0.25y + 0.05y = 280 - 1000
-0.20y = -720
y = -720/0.20
y = 3600
x = 4000 - y
x = 4000 - 3600
x = 400
Hence, the price that he bought each item is given as:
The fan = x = 400
The heater = y = 3600
Answer:
The side length is 2 cm
Step-by-step explanation:
The volume of a cube is s^3
V = s^3
8 = s^3
Take the cube root of each side
8 ^ 1/3 = s^3 ^ 1/3
2 = s
The side length is 2 cm
Answer:
They are both correct.
Step-by-step explanation:
6c=72
We can divide by 6 on both sides and get
c=72/6
Total cans on bottom 4 shelves = 29 x 4 = 116
total cans on top 3 shelves = 42 x 3 = 126
total cans = 116 + 126 = 242 cans
-------------------------------------------------------------
used cans = 56
remaining cans = 242 - 56 = 186 cans
number of cans in each shelf = 9
number of shelves = 186/9 = 20 and 6 cans remaining
remaining 6 cans will be displayed in another shelf
total shelves = 20+1 = 21
