Question

Mr. James expends 1/3 of his monthly income on food, 1/8 of it on clothing and 1/10 of it on children's education. It he still saves Rs. 3180 in a month, find Mr. James's monthly income.

Answer 1

Answer:9600( I think it would be 3280 instead of 3180 . Please check it in the original question)

Step-by-step explanation:

Let the monthly income be X.

Then we get,

X-X{(1/3)+(1/8)+(1/10)}=3280

On solving for X , you'll get,

X=9600..

Therefore, monthly income of Mr. James = 9600 units

Enjoy maths!!!

Answer 2

Answer:

Let the salary be = x

Then, the equation formed will be:

$\frac{x}{3} + \frac{x}{8} + \frac{x}{10} + 3180 = x \\ \\ = > \frac{80x + 30x + 24x + 763200}{240} = x \\ \\ = > 134x + 763200 = 240x \\ = > x = 7200$

Thus, salary = Rs. 7200
