Answer:

The lady had Rs. 500 before she made the pie.

Step-by-step explanation:

(First off, I'm not sure what Rs. means, so I'm going to assume it means rupees.)

Since this lady spent Rs. 150 on a dish and it was 30% of what she had before, we need to make an equation.

x(0.30) = 150,

where x is what the lady had before.

This is relatively easy, where all we have to do is divide each side by 0.30.

[tex]x(0.30) = 150[/tex]

[tex]\frac{x(0.30)}{0.30} = \frac{150}{0.30}[/tex]

[tex]x = 500[/tex]

This lady had Rs. 500 before she started making the dish.

To check, we'll go the easier route: fractions.

[tex]\frac{150}{x} = \frac{3}{10}[/tex]

Then, we need to divide 150 by 3 (which equals 50). Multiply 50 by 10, plug that in for x, and simplify.

[tex]\frac{150}{x} = \frac{150}{50*10} = \frac{150}{500} = \frac{3}{10}[/tex]

Done!

(Actually, I don't know if the fraction route was easier after all! By the way, she had Rs. 350 after she made the dish. I wonder what that dish was?)
