Answer 2

Answer:

Mary has 900 stamps now.

Step-by-step explanation:

Given,

Total stamps John has = 600,

Since, he gave 1/4 of these stamps to Mary,

Also, $\frac{1}{4}\text{ of }600 = \frac{600}{4}= 150$

i.e. he gave 150 stamps to Mary,

Let initially, Mary has x stamps,

Then the new number of stamps Mary has = x + 150,

While, new number of stamps John has = 600 - 150 = 450,

According to the question,

2(x+150) = 450

x + 150 = 900

Hence, Mary has 900 stamps now.
