10% of 1500 = Rs 150
Therefore sold price = 1500 - 150 =Rs 1350
Let x be the amount bought for the product by shopkeeper
Price bought for product by shopkeeper = 120/100 x = 1350
X = 1,125 Rs
Therefore for 12 % profit
112/100 x 1125 = Rs 1260 (final answer)

Answer:
First, we know that:
1 1/3 = 4/3
10 2/3 = 32/3
15 minutes = 0.25 hours
Let's imagine that x (hours) is the time it takes Lee to type 32/3 pages.
From the information, we can tell that:
Lee can type:
4/3 pages in 0.25 hours
32/4 pages in x hours
So x should be:
x = (32/4 . 0.25)/4/3 = 2 (hours)
So it takes Lee 2 hours ro type 10 2/3 pages
12 boards. 21 / 1 3/4 = 12! Hope this helps
2(x+4)=16
multiply the bracket by 2
(2)(x)=2x
(2)(4)=8
2x+8=16
move 8 to the other side, sign changes from +8 to -8
2x+8-8=16-8
2x=16-8
2x=8
divide both sides by 2 to get x by itself
2x/2=8/2
Answer:
x=4
Y=x^2-5, solve for x
y+5=x^2
x=√(y+5) so
f^-1(x)=√(y+5)
