Aman and prakash coloured an entire harry potter colouring book together. the book had 75 pages. aman coloured 60% of the pages. how many pages did prakash colour? a) 30 b) 60 c) 75 d) 45

A) 30 pages

Step-by-step explanation:

No of pages = 75

Aman coloured 60 % of the pages= 75 *60/100= 45

Prakash coloured 75 - 45 = 30 pages

Prakash coloured 30 pages of the book.

Step-by-step explanation:

The total number of pages in the entire Harry Potter Colouring Book is 75. Aman and Prakash coloured an entire Harry Potter Colouring Book together. Aman coloured 60% of the pages. This means that the percentage of the entire Harry Potter Colouring Book that Prakash coloured would be 100 - 60 = 40%

The number of pages that Prakash coloured would be

40/100 × 75 = 0.4 × 75 = 30 pages

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
