$$(a + 2b)^2 - (a - 2b)^2$$ is equal to:

In an equilateral triangle, the value of each exterior angle is:

If x : y = 3 : 2 and x + y = 90. Then the value 7(x — y) : (x + y) is:

The radius of a circular cylinder is 5 cm and its height is 14 cm. Then the volume of cylinder in $$cm^3$$ is:
(Take $$\pi = \frac{22}{7}$$)

Find the values of x for the given equation $$3x^2 + 5x - 2 = 0$$

The given bar graph represents the number of students admitted in four schools (S1, S2, S3, S4) during two consecutive years 2017 and 2018.

What percentage is the average admission of schools S3 and S4 in 2018 of the average admission of schools S1 and S2 in 2017?

The given bargraph represents the number of students admitted in four schools (S1, S2, S3, S4) during two consecutive years 2017 and 2018.

The ratio between total number of students admitted in the four schools in 2017 to the total number of students admitted in the four schools in 2018 is:

Tap A can fill a tank in 20 hours and tap B can fill the same tank in 30 hours. If both taps are opened together, then how muchtime will be taken to fill the tank?

Two tangents AP and AQ are drawn to a circle with centre O from an external point A, where P and Q are points on the circle. If AP = 12 cm and $$\angle PAQ = 60^\circ$$, then the length of chord PQ is:

The given bar graph represents the number of students admitted in four schools (S1, S2, S3, S4) during two consecutive years 2017 and 2018.

The total number of students admitted in school S3 for both years is approximately what percent of total student admitted in school S2 for both years?
