21. एकजना व्यक्तिले बैंक 'p' मा 2 वर्षका लागि रु. 80,000 प्रतिवर्ष 10% को दरमा वार्षिक चक्रीय ब्याज पाउने गरी
जम्मा गरेछ । तर ठीक एक वर्ष पछि बैंकले नीति परिवर्तन
गरी सोही ब्याजदरमा अर्धवार्षिक चक्रीय ब्याज दिने निर्णय
गरेछ । पहिलो वर्षको र दोस्रो वर्षको ब्याज रकममा कति
प्रतिशतले फरक परेछ ? हिसाब गरी कारण लेख्नुहोस् ।
A person deposited Rs 80,000 in bank 'P' for 2 years
at the rate of 10% p. a. compounded annually. But
after one year, bank has changed the policy and
decided to pay semi-annual compound interest at
the same rate. What is the percentage difference
between compound interests of the first year and
second year? Give reason with calculation.​

i dont know sorry

step-by-step explanation:

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

1; 35 is the ratio

step-by-step explanation:

3

step-by-step explanation:

in standard form:

a= dictionaries

b= maps

you have to buy 3 dictionaries, so put a 3 next to the a (dictionaries) so that you can multiply them by each other.

a3+b= 60 (the amount of money you have)

we already know the cost of a=15 so replace a with $15

($15 x 3)+b=60

multiply 15 and 3 to get $45 and replace it with $45

45+b=60

and then replace b with 15 to get the total:

45+15=60

that means you have $15 left after buying 3 dictionaries.

15 divided by the cost of a map ($5) equals 3.

so you can buy 3 maps.

sorry if it was confusing!
