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.
