_________________________________

Solution

So Anuja spent 70% of her total money. So now she has 30% of the total money left. (100 - 70 = 30)

So now, we have to solve this equation to find the amount Anuja had in the start ⇒ 30% × x = 900

Let's solve your equation step-by-step.

Step 1: Convert 30% in fractional form.

$→ \dfrac{30}{100} \times x = 900 </p><p>$

$→ \dfrac{3}{10} \times x = 900$

Step 2: Multiply both sides with ¹⁰/₃

$→ \dfrac{10}{3} \times \dfrac{3}{10} \times x = \dfrac{10}{3} \times 900 </p><p>$

$→ x = 10\times 300x=10×300$

∴ Anuja had Rs. 3000 in the beginning.
