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 ?
Answers
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
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.
