Answer:
Part A Answer = A=28
Part B Answer is B = 9/16 + C =0.56
Step-by-step explanation:
1 = A. 28 This is because the percentage rate works out at 43.75%
2. 9/16 also, 0.56 This is because 9/16 has decimal 0.56 we can work this out by looking at the inverse of 1 ; 1= 16 16/9 = 1.77/3.17 which adds to 4.94 = 10 x 0.49 4 representing 4 from 20 =16 and 9 representing the proportion.
Answer:
60,000
Step-by-step explanation:
Let us represent:
Costs price = x
Selling price = x - 25%x
x - 0.25x
= 0.75x
If it been sold for Rs 21,000 more then the profit would have been
10%. = x + 10% = 1.1x
1.1x =0.75x + 21000
Collect like terms
1.1x - 0.75x = 21000
0.35x =21000
x = 21000/ 0.35
x = 60000
The cost price of the item = 60,000

Answer:
y = 2
Step-by-step explanation:
Given
= ( cross- multiply )
10(2y - 1) = 15y ← distribute left side
20y - 10 = 15y ( subtract 15y from both sides )
5y - 10 = 0 ( add 10 to both sides )
5y = 10 ( divide both sides by 5 )
y = 2
The answer is 9t hope this helps
