The given Bar Graph presents the number of students of two schools for six years.

What is the ratio of the number of students taken together for the years 2008, 2012 and 2013 in School A to the number of students taken together for the years 2008, 2012 and 2013 in school B?

A man bought three articles for ₹3,000 each. He sold the articles respectively at 10% profit, 5% profit and 15% loss. The total percentage profit/loss he earned is:

A and B can complete a piece of work in 15 days and 10 days respectively. They got a contract to complete the work for ₹75000. The share of B (in ₹) in the contracted money will be:

If $$4(\cosec^2 65^\circ - \tan^2 25^\circ) - \sin 90^\circ - \tan^2 63^\circ y \tan^2 27^\circ = \frac{y}{2}$$, then the value of $$y$$ is:

If each side of a rectangle is decreased by 13%, then its area will decrease by:

If $$\cos x = \frac{-\sqrt3}{2}  and  \pi < x < \frac{3\pi}{2}$$, then the value of $$2 \cot^2 x - 3 \sec^2 x$$ is:

The average age of fifteen persons is 32 years. If two more persons are added then the average is increased by 3 years. The newpersons have an age difference of 9 years between them. The age (in years) of the elder among the new persons is:

If $$\cot \theta = 5x  and  \cosec \theta = \frac{5}{x}$$(x ≠ 0), then the value of $$5\left(x^2 - \frac{1}{x^2}\right)$$ is:

In which year the percentage increase in the number of total students in schools A and B taken together is the highest in comparison to its previous year?

What is the average (Correct to two decimal places) of total students in schools A and B taken together during the six year period?
