There are 16 red shirts and some black shirts hanging in the store. The ratio of the number of red shirts to that of black shirt

WITCHER [35]

Answer:

If 5 red shirts are added into the box, 7 : 8 is the new ratio.

Step-by-step explanation:

The number of red shirts = 16

Let the number of black shirts = k

Now as the ratio of Red Shirts : Black Shirt = 2 : 3

By RATIO OF PROPORTIONALITY:

⇒ $\frac{16}{k} = \frac{2}{3}$

or, $k = 16 \times \frac{3}{2} = 24$

Hence, the number of Black Shirts in the Store = 24

Now, new number pf red shirts = 16 + 5 = 21

So, by the proportionality again, ratio is

$\frac{21}{24} = 7:8$

Hence, the new ratio of Red shirts : Black Shirts = 7 : 8
