. एकजना व्यक्तिले बैङ्क 'p' मा 2 वर्षका लागि रु. 55,000 वार्षिक 10%

नीति परिवर्तन गरी सोही ब्याजदरमा अर्धवार्षिक चक्रीय ब्याज दिने निर्णय
गरेछ। पहिलो वर्ष र दोस्रो वर्षको ब्याज रकममा कति प्रतिशतले फरक
परेछ ? हिसाब गरी कारण लेख्नुहोस्।
A person deposited Rs. 55,000 in bank 'p' for 2 years at 10%
compound interest compounded annually. But after one year
bank has changed the policy and decided to semi-annual,
compound interest at the same rate. What is the percentage
difference between the compound interests of the first year
and second year? Give reason with calculation.

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240

perimeter = 10 +  √10  units

explanation:

first, we will need to get the length of each line using the distance formula which is as follows:

distance = 

1- length of ab:

ab =   = 5 units

2- length of ac

length of ac is the same as ab = 5 units

3- length of bc:

bc =   =  √10  units

now, we can get the perimeter by adding the side lengths as follows:

perimeter = 5 + 5 +  √10

perimeter = 10 +  √10  units

hope this : )
