bonkysleuth SG The average age of a group containing of a group of scientists and engineers is 40. If the scientists average age is 35 and the engineers' average age is 50, find the ratio of the no. of scientists to the number of engineers.Please lend a hand in solving this! thanks
SBS n SMRT SG let no of scientist be x, engineer be y40 = (35x + 50y ) / (x+y)40 x + 40 y = 35 x + 50 y5x = 10 yRatio of x : y is 2: 1
