Answer:
the cost price is Rs. 4500 and the sale price is Rs. 5040.
Step-by-step explanation:
Let the cost price of the compute be Rs. x.
The profit earned is, Rs. 540.
The profit percentage is, 12%.
The formula to compute profit is:
Profit = SP - CP
\begin{gathered}540=x[1+\frac{12}{100}]-x\\540=1.12x-x\\540=0.12x\\x=\frac{540}{0.12}\\x=4500\end{gathered}540=x[1+10012]−x540=1.12x−x540=0.12xx=0.12540x=4500
Compute the selling price as follows:
SP = CP + profit
= 4500 + 540
= 5040
Thus, the cost price is Rs. 4500 and the sale price is Rs. 5040.

Step-by-step explanation:
Since the triangles are similar then the ratios of corresponding sides are equal, that is
=
, substitute values
=
( cross- multiply )
4XZ = 144 ( divide both sides by 4 )
XZ = 36 cm

( cross- multiply )
16BC = 192 ( divide both sides by 16 )
BC = 12 cm
Answer: D
Step-by-step explanation: common sense
The numbers are part of an arithmetic progression, where the difference between each succeeding number is reduced by 1 each time. Between 107 and 98, the difference is 9. Between 98 and 90, the difference is 8, and so on. This is shown below:
107 - 98 = 9
98 - 90 = 8
90 - 83 = 7
83 - 77 = 6
77 - x = 5
x - 68 = 4
68 - 65 = 3
From that, we can solve for x using either of the equations:
77 - x = 5
x = 77 - 5
x = 72
Therefore 72 would complete the pattern.
Answer:
$600
Step-by-step explanation:
Given data
Principal= $10000
Time = 3 years
Rate= 2%
The simple interest formula is expressed as
SI= PRT/100
substitute
SI= 10000*2*3/100
SI= 60000/100
SI= 600
Hence he will earn $600 in interest
