Question

if the numerator of a fraction is decreased by 1 and the denominator is decreased by 2 the fraction becomes 1/2 if the numerator and denominator increased by 2the fraction becomes 1/2 find the fraction​

Answer 1

Answer:

∴A deposit of 6500 was invested and expanded to 8300 , this means the simple interest is

= 8300 - 6500

= $ 1800

∴ Principal = $6500

∴No. of years = 5 years

∴Simple interest = $1800

\begin{gathered} = > 1800 = \frac{6500 \times r \times 5}{100} \\ \\ = > 1800 \times 100 = 6500 \times r \times 5 \\ \\ = > 180000 = 32500 \times r \\ \\ = > r = \frac{180000}{32500} \\ \\ = > r = 5.5\%\end{gathered}

=>1800=

100

6500×r×5

=>1800×100=6500×r×5

=>180000=32500×r

=>r=

32500

180000

=>r=5.5%

ANS- Rate of interest = 5.5%
