Correct Answer - Option 3 : 20%
Given:
10 Kg ghee pack contains 60% pure ghee and 40% vanaspati ghee.
10 Kg of pure ghee is added to the mixture of 10 Kg ghee pack.
Formula used:
Percentage of vanaspati ghee in final mixture = (Quantity of vanaspati in final mixture / Total quantity of final mixture ) × 100
Calculation:
According to the question,
60% of pure ghee in initial mixture = (60/100) × 10 Kg = 6 Kg
40% of vanaspati ghee in initial mixture = (40/100) × 10 Kg = 4 Kg
After adding 10 Kg of pure ghee,
Total quantity of final mixture = 10 Kg + 10 Kg = 20 Kg
Quantity of vanaspati ghee in final mixture = 4 Kg
⇒ Percentage of vanaspati ghee in final mixture = (4/20) × 100
⇒ 0.2 × 100 = 20 %
∴ The percentage of vanaspati ghee in final mixture is 20 %.
