In what ratio should fertilizer costing Rs. 270 per bag be mixed with fertilizer costing Rs. 320 per bag so that the cost of the mixture is Rs. 300 per bag. (A bag of fertilizer is 30 kg)

In what ratio should fertilizer costing Rs. 270 per bag be mixed with fertilizer costing Rs. 320 per bag so that the cost of the mixture is Rs. 300 per bag. (A bag of fertilizer is 30 kg) Correct Answer 2 : 3 

Given:

CP of fertilizer1 = 270/bag

CP of fertilizer2 = 320/bag

CP of mixture = 300/bag

Calculations:

Required ratio = (320 – 300)/(300 – 270)

⇒ 20/30

⇒ 2 : 3

∴ Required ratio is 2 : 3.
