The proportion would look like:-
118 59
------- = --------
13 z
Solve for z:-
13 × 59 = 767
767 ÷ 118 = 6.50
so z = 6.50
Check your work
118 × 6.50 = 767
13 × 59 = 767
So, z = 6.50

Step-by-step explanation:
Here :-
- Selling price of 10 mangoes is equal to the cost price of 12 mangoes
Let the cost price of one mango be ₹1. So :-
- Cost Price of 10 mangoes = ₹10
- Selling Price of 10 mangoes = ₹12
↝ Here the selling price of 10 mangoes is equal to the cost price of 12 mangoes. It means selling price of 10 mangoes = cost price of 12 mangoes. So, the selling price of 12 mangoes is ₹12 and the cost price of 10 mangoes is ₹10.
<em>Fistly, finding the profit :-</em>
∴ The profitis Rs.2.
<em>Now, finding the profit percentage :-</em>
∴ The profit percent is 20%.
Solve for x over the real numbers:
2 x^2 - 4 x - 3 = 0
Divide both sides by 2:
x^2 - 2 x - 3/2 = 0
Add 3/2 to both sides:
x^2 - 2 x = 3/2
Add 1 to both sides:
x^2 - 2 x + 1 = 5/2
Write the left hand side as a square:
(x - 1)^2 = 5/2
Take the square root of both sides:
x - 1 = sqrt(5/2) or x - 1 = -sqrt(5/2)
Add 1 to both sides:
x = 1 + sqrt(5/2) or x - 1 = -sqrt(5/2)
Add 1 to both sides:
Answer: x = 1 + sqrt(5/2) or x = 1 - sqrt(5/2)
