Answer 2

Answer:

(i) 25 %

(ii) 64%

(iii) 1%

(iv) 75%

Step-by-step explanation:

(i)Total no. of students = 32

No. of students absent = 8

∴ Percentage of students = $\frac{8*100}{32}$ = 25 %

(ii)Total no. of radios =  25

No. of radios out of order = 16

∴ Percentage of defective radios = $\frac{16*100}{25}$ = 64%

(iii)Total no. of items = 500

No. of items defective = 5

∴ Percentage of items defective =$\frac{5 *100}{500}$ = 1%

(iv)Total no. of voters = 120

No. of voters voted yes =90

∴ Percentage of voters voted yes  =$\frac{90 *100}{120}$ =75%
