Can someone please help me out with this? Thank you

(D) 48

Step-by-step explanation:

Given,

The ratio of the number of Jackie's pink T-shirts to the number of her purple T-shirts = 4:3

Let pink T-shirts = 4x, purple shirts = 3x

Where,

x is any positive real numbers,

So, the total number of her pink and purple T-shirts = 4x + 3x = 7x

Since, 7x is the multiple of 7,

28, 42 and 70 are the multiple of 7,

So, they can be the total number of shirts,

But, 48 is not the multiple of 7,

Hence, 48 can not be the total number of her pink and purple T-shirts.
