give me this question answer ​

Answer 1

Answer:

15

Step-by-step explanation:

Let the students who like the red coloured dresses be 4x

and, the students who like the blue coloured dresses be 3x

A/Q

4x+3x+16 = 51

7x+16 = 51

7x = 51 -16

7x = 35

x = 35/7

x = 5

Hence, the student like the blue coloured dresses = 3x = 3×5 = 15
