Question

0. Gauri spends 0.75 of her salary every month. If she earns Rs. 12,000 per month, in how many
months will she save Rs. 39,000 ?

Answer 1

see, her monthly salary is 12,000.

she spends in one month - 0.75*12,000 = 9000

savings in one month = 12000–9000= 3000

so in month savings are rs3000

so savings will become

39000 in = 39000/3000=13 months or 1 year 1month

Answer 2

Step-by-step explanation:

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

=25×12000

=25 / 100 × 12000

=3000

Gauri has to save = Rs 39000.

∴ Number of months Gauri needs to save Rs 39000

= (Rs3000) / (Rs39000)

= 13 months.

The number of months Gauri needs to save Rs 39000 is 13 months.
