Question

A seed store has 300 kg of lawn seed which is a mixture of three fourth rye grass and one fourth blue grass . How much blue grass must be added to make a mixture that is half rye grass and half blue grass?​

Answer 1

Hey Dear,

◆ Answer -

Blue grass to be added = 250 kg

◆ Explanation -

Presently amount of rye grass in lawn is -

Rye grass = 300 × 3/4

Rye grass = 225 kg

Presently amount of blue grass in lawn is -

Blue grass = 300 × 1/4

Blue grass = 75 kg

To make half-half mixture, amount of blue grass must be made equal to rye grass.

Blue grass to be added = Rye grass - Blue grass

Blue grass to be added = 325 - 75

Blue grass to be added = 250 kg

Therefore, 250 kg of blue grass must be added to make half-hapf mixture.

Best luck...
