If `(0.3 (3x -4))/(5) + (0.4 x + 3.6)/(5) = 3.5x` then x = ____A. `0.1`B. `0.3`C. `0.5`D. `0.2`

Answer» Correct Answer - C
`(0.3(3x-4))/(5) + (0.4 x+ 3.6)/(2) = 3.5x`
`(0.9x - 1.5)/(5) + (0.4x + 3.6)/(2) = 3.5x`
`(1.8x - 2.4 + 2.0x + 18)/(10) = 3.5x`
`3.8 x + 15.6 = 35x`
`15.6 = 31.2x`
`x = (15.6)/(31.2)`
`x = (1)/(2)` ltbr. `:. x = 0.5`
Hence, the correct option is (c)
