Barnika bought 100 eggs for Rs. 900. Out of them. 8 were broken. She sold the remaining eggs
at the rate of Rs. 10.50 each. Find the profit or loss
percent.

Step-by-step explanation:

cost of an egg= 900/100= Rs.9

Total cost = 100×9=Rs.900

when 8 eggs broken, the eggs remained to sell is 92(100-8)

Total sales = 10.50×92=Rs.966

profit = total cost-total sales

profit =966-900= Rs.66

profit percentage =profit/total sales×100%

66/966×100%=6.832%

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).
