Question
Which of the following ratios can help compare the
operational efficiency of different entities?Solution
 Assets turnover ratio shows how much sales an entity is generating with the use of assets. This is an efficiency ratio.
If x = (2+√3)/(2-√3), y = (2-√3)/(2+√3)
Then find out the value of (x²+y²-xy)/(x²+y²+xy)
 `sqrt(sqrt(17+sqrt(17+sqrt(17)) ... prop)`  = ?
If (2a + b)/(3b - 2b) = 13/2 then 'b' is what percent of 'a'?
If x2 – 10x + 20 = 0, then find the value of (x – 3)2 + 1/(x – 3)2
The coefficient of ‘b2’ in (3a + b)3 is
If (a2 + 1/a2) = 18, then find the value of (a3 - 1/a3).
What is the value of (a² + b²+4c²- ab-2bc-2ca) (a + b+2c):
√4096 + √(?) + 13 – 29 = 148Â
 `sqrt(sqrt(10-sqrt(10-sqrt(10)) ... prop)` = ?
- If (a 2  + 1/a 2 ) = 66, then find the value of (a 3  – 1/a 3 ).
