सरल करें: `(0.41xx0.41xx0.41+0.69xx0.69xx0.69)/(0.41xx0.41-0.41xx0.69+0.69xx0.69)`

Options

A. `0.28`
B. `1.41`
C. `1.1`
D. `2.8`

Answer

C

Explanation

`(0.41xx0.41xx0.41+0.69xx0.69xx0.69)/(0.41xx0.41-0.41xx0.69+0.69xx0.69)`
`implies ((0.41)^(3)+(0.69)^(3))/((0.41)^(2)-0.41xx0.69+(0.69)^(2))`
`:' [a^(3)+b^(3)=(a+b)(a^(2)+b^(2)-ab)]`
`implies 0.41+0.69=1.10`
