Answer 1

Step-by-step explanation:

Given :-

Principle = Rs. 256

Rate of interest = 100% per annum

Time = 1 year

To find:-

Find the compound interest and amount ?

Solution :-

Given that

Principle = Rs. 256

Rate of Interest = 100% per annum

If interest is calculated compounded quarterly then for 1 year = 4 times

Rate of interest = 100%/4 = 25%

We know that

Amount =P[1+(R/100)]^n

=> A = 256[1+(25/100)]⁴

=> A = 256[1+(1/4)]⁴

=> A = 256[(4+1)/4]⁴

=> A = 256[(5/4)⁴

=> A = 256×5×5×5×5/4×4×4×4

=> A = 256×625/256

=> A = Rs. 625

We know that

Amount = Principle + Interest

=> Interest = Amount - Principle

=> Interest = 625-256

=> I = Rs. 369

Answer:-

Amount for the given problem is Rs. 625

Compound Interest for the given problem is

Rs. 369

Used formulae:-

• Amount =P[1+(R/100)]^n

• Amount = Principle + Interest
