Answer:
The number of months Gauri needs to save Rs 39000 is 13 months.
Solution:
Total salary of Gauri = Rs 12000 per month.
Every month she spends = 0.75 part of her salary.
Assuming she saves the entire part of her salary left after spending 0.75 parts,
Thus, every month she saves = 1 – 0.75 part of her salary.
= 0.25 parts of her salary.
Savings of Gauri every month = 0.25 part of Gauri’s salary every month
\begin{gathered}\begin{aligned} & = 0.25 \times \mathrm { Rs } 12000 \\\\ & = \frac { 25 } { 100 } \times R s. 12000 \\\\ & = 25 \times \mathrm { Rs } 120 \\\\ & = \mathrm { Rs } 3000 \end{aligned}\end{gathered}
=0.25×Rs12000
=
100
25
×Rs.12000
=25×Rs120
=Rs3000
Gauri has to save = Rs 39000.
∴ Number of months Gauri needs to save Rs 39000
= \frac {(Rs 39000)}{(Rs 3000)}
(Rs3000)
(Rs39000)
= 13 months.
The number of months Gauri needs to save Rs 39000 is 13 months.
