This is a sum and difference problem, with the equations
R-N=35
R+N=635
The solution of which is
R=(635+35)/2=335
N=(635-35)/2=300
In general, the sum and difference problem can be solved (most of the time mentally) using
Larger number = (sum + difference)/2
Smaller number = (sum - difference)/2
Answer:

Step-by-step explanation:
we know that
The simple interest formula is equal to

where
I is the Interest Value
P is the Principal amount of money to be invested
r is the rate of interest
t is Number of Time Periods
in this problem we have

substitute in the formula above


Lets say the final price of the bike is SP plus 13% VAT. So:
1.13 * SP = 6356.25
SP = 5625
Now SP was after 10% discount on Original Price, say MP. So:
0.9 * MP = 5625
MP = 6250
Therefore, the percent of Marked Price above Cost Price is:
(6250 - 5000) * 100/5000 = 25%
Answer: 30/a
Step-by-step explanation:
Quotient means to divide. So the quotient of 30 and another number would be 30/a
