<h3><u>Question:</u><u>-</u></h3>
A coca cola costs 150 yen. You buyed 30 bottles of cola and sold them at the price of 155 yen each. Find profit %
<h3><u>Answer</u><u>:</u><u>-</u></h3>
3.33%
<h3><u>Explanation</u><u>:</u><u>-</u></h3>
Cost price = ¥150
Selling price = ¥155
Total profit = Selling price - Cost price
→ = ¥155 - ¥150
→ = ¥5
Profit % = Profit × 100/cost price
️ = 5 × 100/150
️ = 10/3 = 3.33%
Answer:
<u> </u><u>y</u><u> </u><u>is</u><u> </u><u>the</u><u> </u><u>cube</u><u> </u><u>root</u><u> </u><u>of</u><u> </u><u>2</u><u>7</u><u> </u>
Step-by-step explanation:
![{ \tt{ {y}^{3} = 27 }} \\ \\ { \tt{y = \sqrt[3]{27} }} \\ \\ { \tt{y = 3}}](https://tex.z-dn.net/?f=%20%7B%20%5Ctt%7B%20%7By%7D%5E%7B3%7D%20%3D%2027%20%7D%7D%20%5C%5C%20%20%5C%5C%20%7B%20%5Ctt%7By%20%3D%20%20%5Csqrt%5B3%5D%7B27%7D%20%7D%7D%20%5C%5C%20%20%5C%5C%20%7B%20%5Ctt%7By%20%3D%203%7D%7D)
So here we have similar parallelograms. Which means, that 24/16 must equal to y/4.
24/16=y/4
3/2=y/4
4•3=2•y
12=2y
y=6
