Answer:
let cp be x
rs 100 is decreased of 10%,
Step-by-step explanation:
Answer:
let cp be x
rs 100 is decreased of 10%,
(10/100)× x,. 90x/100 is now the price
then it is increased by 25 % ,
(90x/100)+25/100,. now the price is 115x/100
therefore after this we get an equation,
\begin{gathered} \frac{115x}{100} = rs \: 90 \\ \\ x = \frac{90 \times 100}{115} \end{gathered}
100
115x
=rs90
x=
115
90×100
so x, is equal to approximately rs 78.20
