Question

solve it.........
with proper solution....

Answer 1

ley p be the sum of money and no. of years be 2 .

rate of interest 5%

simple interest = p×2×5/100

compound interest = p(1+5/100)²-p

given that difference is 25 .

now ,

p(1+5/100)²-p - p×2×5/100 = 25

p(1+1/20)²-p-p/10b= 25

p{(21/20)²-1-1/10}= 25

p(441-400-40/400)=25

p(441-440/400) = 25

p(1/400) = 25

p = 25×400

p = 10000

thus the sum of money is rupee 10000

hope that helps
