Answer 2

Answer:

She have Rs.64 in the beginning .

Step-by-step explanation:

Let x be the initial amount

She spends  1/4 of her pocket money on chocolates

So, amount spent on chocolates = $\frac{x}{4}$

She spent 1/8 on crayons

So, amount spent on crayons = $\frac{x}{8}$

So, Total amount spent =  $\frac{x}{8}+\frac{x}{4}=\frac{3x}{8}$

Amount left = $x-\frac{3x}{8} =\frac{5x}{8}$

We are given that  At the end she had Rs.40 left.

So, $\frac{5x}{8}=40\\5x=320\\x=64$

So, She have Rs.64 in the beginning .
