Answer:
$15.6
Step-by-step explanation:
First, let's assume that <em>x</em> is the total money in the bag of coins.
1. <em>x</em> = total money
4/13 of the coins are pennies, so 4/13 of x equals to the number of pennies.
4/13(x) = P (pennies)
What is left that is not pennies is 9/13(x). And out of these, 1/4 are nickels. Which means:
1/4(9/13[x]) = N (nickels)
If 1/4 of the remaining are nickels, then 3/4 are dimes. So:
3/4(9/13[x]) = $8.10 (dimes' value)
After calculating the one with the value:
27/52(x) = $8.10
27x = $8.10 times 52
x = ($8.10 times 52)/27
x = 52 x $0.3
x = $15.6
Ans. The value of the bag of coins is $15.6
What we have to solve is:
we should multiply both sides by10, to get the "x" by itself:
so there are 8 tenths in this number!
Here
Principal(P)=15000
Time(T)=2years
Rate(R)=5% p.a.
Interest(I)=PTR/100
=15000*2*5/100
=1500
Amount(A)=P+I
=15000+1500
=16500
Given : Kishore bought a basket containing 30 oranges for rs 310. If he sells the oranges at rs 12 each , what Would be it's profit or loss?
Solution :
Cost price of oranges = rs.310
As we know that each oranges cost rs.12
So, selling price of oranges is 30 × 12 = rs.360
Now, <u>finding profit or loss</u>
Profit = Selling Price - Cost Price
Profit = rs.360 - rs.310
Profit = rs.50
