workers decided to raise rs . 3 lacs by equal contribution from each . had they contributed rs . 50 eachextra , the contribution would have been rs . 3.50 lacs . how many workers were they ?
"n * 50 = ( 350000 - 300000 ) = 50000 n = 50000 / 50 = 1000 e"
divide(multiply(multiply(subtract(3.50, 3), const_1000), const_100), 50)
