The given histogram shows the marks scored by 40 students in a test of maximum 30 marks.
What is the percentage of students who scored less than 50% marks?
The value of \(\dfrac{12.5 + \dfrac{4}{7} \text{ of } 56 - 12}{(207 \div 23 \times 4.5) - 21\dfrac{1}{3} \times \left(\dfrac{1}{4} + \dfrac{1}{8}\right)}\) is:
If K -\(\dfrac{3}{k}\) = 5, then what is the value of \(k^{2} + \dfrac{9}{k^{2}}\)?
What number should be subtracted from
\(4(\sin^{4}60^{\circ}+\cos^{4}30^{\circ})-(\tan^{2}45^{\circ}-\cot^{2}30^{\circ})+\cos^{2}45^{\circ}-\csc^{2}45^{\circ}+\sec^{2}60^{\circ}\ \text{to get }2?\)
Study the given pie charts and answer the question that follows. The pie charts show the distribution of students of graduate and postgraduate levels in five different institutes P, Q, R, S and T in a town.
(i) Total number of students of graduate level in five different institutes = 12400
(ii) Total number of students of post graduate level in five different institutes = 8000.
The ratio of the number of students of graduate level in Institutes P and S together to that of post graduate level in institutes P and S is:
