the average salary of all the workers in a workshop is rs . 8000 . the average salary of 7 technicians is rs . 11000 and the average salary of the rest is rs . 6000 . the total number of workers in the workshop is
"sol . let the total number of workers be x . then , 8000 x = ( 10000 × 7 ) + 6000 ( x – 7 ) ‹ = › 2000 x = 28000 ‹ = › x = 14 . answer a"
add(7, divide(multiply(7, subtract(11000, 8000)), subtract(8000, 6000)))
