Question

A house is decorated with chains of small blue and green lights. If the ratio of the chains of blue and green light is 5:4 and the total number of blue lights is 1765, then determine the number of green lights.​

Answer 1

Answer:

Number of blue lights = 5x

Number of green light = 4x

∴Total number of lights = 5x+4x

9x = 1765

 x =$\frac{1765}{9}$

x = 196

4x = 4×196= 784
