Step-by-step explanation:
Given How many kg of custard powder costing Rs. 42 per kg must be mixed with 16 kg of custard powder costing Rs. 60 per kg so that 20 % may be gained by selling the mixture at Rs. 60 per kg?
- Given Selling price is Rs 60 for 1 kg
- Also profit or gain is 20%
- So cost price = S.P x 100 / 100 + profit percent
- = 60 x 100 / 100 + 20
- = 6000 / 120
- = 50
- So the ratio of custard powder will be 60 – 50 = 10 and 50 – 42 = 8
- So it will be 10:8
- Now if p is the quantity of custard powder to be mixed we have
- 10:8 = p :16
- 10/8 = p/16
- 8p = 160
- Or p = 160 / 8
- Or p = 20 kg
