Question

Dr. Ritam deposited 25% of her money in a bank. After spending 20% of the remainder,
she has 6,000 left with her. How much did she originally have?​

Answer 1

Answer:

Let's consider original money to be ₹x

So first let's calculate the remainder

= x - $\frac{25x}{100}$

= $\frac{100x - 25x}{100}$

= $\frac{75x}{100}$

ATP, $\frac{75x}{100}$ - $\frac{20}{100}$  x $\frac{75x}{100}$ = 6000

=> $\frac{75x}{100}$ - $\frac{3x}{20}$ = 6000

=> $\frac{75x - 15x}{100}$ = 6000

=> $\frac{60x}{100}$ = 6000

=> $\frac{6x}{10}$ = 6000

=> 6x = 60000

=> x = $\frac{60000}{6}$

=> x = 10000
