Q mixture contains substance a and substance B on the ratio 7:9if the total weight of the mixture is 48 kg ?find the weight of substance B

Answer 1

Answer:

27kg

7:9---- 7x:9x=16x. where A is 7x and b is 9x

7x + 9x = 48 (As total combination of substance A and B is 48kg)

16x = 48

x = 48/16 = 3kg

9x = 9 x 3 = 27kg

So the weight of substance B is 27 kg
