Question

Alka spends 90 % of the money that she receives every month, and saves Rs. 150. How much

money does she get monthly?​

Answer 1

Answer:

1200

Step-by-step explanation:

Let the total money be x

now, money she spend = 90x/100

Money she have =120

Now,

⇒

$\frac{90x}{100 } + 120 = x$

=>

$x - \frac{90x}{100} = 100$

=>

$\frac{10x}{100} = 120$

=>

$\frac{120 \times 100}{10}$

=> x = 1200

She earn 1200.
