The volume of a right circular cone is equal to that of a sphere, whose radius is half the radius of the base of the cone. What is the ratio of the radius ofthe base to the height of the cone ?

if (a+b+4){ab+4(a+b)}-4ab=0, and a≠-4, b≠-4, then ( $$\frac{1} {(a+b+4)^{117}}-2^{-234}$$) is equal to

The simplified value of 

$$\left\{\frac{3}{4} of \frac{4}{15}\times1\frac{2}{3}-\left(3\frac{1}{2}-2\frac{1}{6}\right)\right\}$$

The given Bar Graph presents the sale of a particular brand of car by three showrooms, A, B and C (in multiples of 100) during the months Jan, Feb, Mar and Apr, 2016.

What was the average number of cars sold by A during Feb-Apr, 2016?

For $$ 0^\circ < \theta < 90^\circ$$, $$tan\theta + cot\theta$$ = 2 is equal to:

The given Bar Graph presents the sale of a particular brand of car by three showrooms, A, B and C (in multiples of 100) during the months Jan, Feb, Mar and Apr, 2016.

If the cars sold by A and B are all found to be in perfect order, but the cars sold by C were found to be defective to the extent of 15%, 10%, 8% and 6%,respectively in Jan, Feb, Mar and Apr 2016, then what is the ratio of non-defective cars sold by C to that of all cars sold by A and B during Jan-Mar 2016 ? 

Given  $$a+\frac{1}{a}$$=2  what is the value of $$a^{118}+\frac{1}{a^{117}}$$
