Study the given pie chart and answer the question that follows.
Distribution (Degree wise) of students studying in schools A, B, C, D and E
Total Number of students =9000

The number of students in School E exceeds the total number of students in school A and B by x, where x lies between:

ABCD is cyclic quadrilateral and O is the center of the circle. If ∠COD = 140^o and ∠BAC= 40^o, then the value of ∠ BCD is equal to-

Study the given pie chart and answer the question that follows.
Distribution (Degree wise) of students studying in schools A, B, C, D and E
Total Number of students =9000

If the ratio of the number of boys to that of girls in school C is 6 : 5 and that in school B is 7 : 11,then what is the ratio of the number of boys in school C to the number of girls in school B?

X and Y are centres of circles of radius 9 cm. and 2 cm respectively XY=17 cm. Z is the centre of a circle of radius r cm which touches the above circles externally. Given that - ∠xzy = 90^o the value of r is -

Study the given graph and answer the question that follows.

The total number of students obtaining less than 50 marks is what percentage more than the total number of students obtaining 60 marks or more ( correct to one decimal place).

Study the given graph and answer the question that follows.

If 60% of the total number of students obtaining 50 marks or more but less than 70 marks are girls and 55 % of the total number of students obtaining 70 marks or more but less than 90 marks are also girls. Then the total number of girls obtaining 50 marks or more but less than 90 marks is:

If $$ {66{2\over 3}}{ \%}$$ of 75 % of one-eighth of a certain number is 179, then $$ {33{1\over 3}}{ \%}$$ of three – fourth of that number is:

If a =500, b=502 and c=504, then the value of a³ +b³ +c³-3abc
