the balance he spends 25% for children's
education, out of the balance he spends 10% for
transportation finally saves 1080 per month. Find
his monthly salary.​

Answer 1

Answer:

Total % Of Income He Spends = 20% + 25% + 10% = 55%

Remaining Percentage = 45%

That Means 1080 × 45/100 = 486

Monthly Salary is 100%

So, 486 × 100 = 48600

I Hope it helps you and maybe a correct answer.

Answer 2

His monthly salary would be Rs. 2000.

Step-by-step explanation:

Since we have given that

Percentage of his income on food = 20%

Percentage of balance income spends for children = 255

Percentage of balance income spent for transportation = 10%

Amount he saves = Rs. 1080

Let the monthly salary be 'x'.

According to question, it becomes,

$\dfrac{80}{100}\times \dfrac{75}{100}\times \dfrac{90}{100}\times x=1080\\\\\dfrac{72}{100}\times \dfrac{3}{4}\times x=1080\\\\x=\dfrac{1080\times 400}{72\times 3}\\\\x=2000$

Hence, his monthly salary would be Rs. 2000.
