Answer:

hope it helps

Step-by-step explanation:

Answer:

Total percentage of students = 100 %

∴ 50students = 100% – (30% + 20% + 25% + 15%)

= 100% – 90%

50 students = 10%

10% of total students = 50

∴ 10100 (Total students) = 50

Total students = 50×10010 = 500.

Total students = 500.

(i) 20% of the students like red colour.

(ii) 15% of the students liked green colour.

15100 × 500 = 75 students liked green colour.

(iii) 25% students liked blue students liked blue.

⇒ 25100 students liked blue.

⇒ 14 students liked blue.

(iv) Percentage of students liked red colour

= 20%

Percentage of students did not like red colour

= 100% – 20%

= 80%

∴ Number of students did not like red colour

= 80% of 500

= 80100 × 500 = 400

400 students did not like red colour.
