The ratio in which they should be blend together is 7:4.
Step-by-step explanation:
Let the density of 1st metal be x and the 2nd metal be y.
According to the question.
20x + 9y/ x + y = 16
20x + 9y = 16( x + y)
20x + 9y = 16x + 16 y
20x - 16 x = 16y - 9y
4x = 7y
x/y = 7/4
thus the ratio in which they should be blend together is 7:4.
