The following pie diagram shows information about the number of students who like a particular type of breakfast items prepared by hostel chef. The number of total students in the hostel is 3200.

Which of these statements is NOT true?

​Solution:

​The number of total students in the hostel is 3200.​

In Pie chart total percentage = 100%

100% = 3200

1% = $$\frac{3200}{100}$$​​

1% = 32

Then,

Cornflakes = 25% = 25 × 32 = 800

Plum cakes = 25% = 25 × 32 = 800

Eggs = 5% = 5 × 32 = 160

Idly =  15% = 15 × 32 = 480

Bread = 30% = 30 × 32 = 960

Then, 

By option (a),

Option (a) follow.

By option (b),

Idly = 480
Both are equal.

then,

but option (d) not follow,

hence, option (d) is correct.
