How to solve geometric mean

Posted by Prasun Shahi 8 years ago

CBSE > Class 11 > Mathematics

1 answers

Amar Kumar 8 years ago

The Geometric Mean is a special type of average where we multiply the numbers together and then take a square root (for two numbers), cube root (for three numbers) etc.
Example: Geometric Mean of 2 and 18
First we multiply them: 2 × 18 = 36
Then (as there are two numbers) take the square root: √36 = 6
In one line: Geometric Mean of 2 and 18 = √(2 × 18) = 6

Ques-if on 31 july 1993 it was Friday so wht will on 31 july 2001? Firstly in 2000 we will find no. Of odd days 2000÷4=500 as it is totally divisble so no. Of odd days will be zero In case of 2001 no.if odd days=2001÷4=500.25 so there will be odd days,so in 2001 we will count down like-jan =31,feb=28,march=31;april=30,may=31,june=30!and July =31 now 31+28+31+30+31+30+31=212 now we will divide it by no.of weeks =212÷7= in this case 2 will be reminder thus,sunday=0,Monday =1,Tuesday =2 and so on......................so Tuesday will be corct answer
