Question

Fresh mango consists of 70% water and dry mango consists of 10% water then 20kg of fresh mango is equivalent to how much of dry mango

Answer 1

Water content is reduced from 70% to 10% for the dried mango

Find the amount of water in 20 kg of fresh mango:

20 kg of fresh mango = 70% of water = 0.7 x 20 = 14 kg

Find the amount of non-water in 20kg of fresh mango:

20 - 14 = 6kg

Find the weight of the dried mango:

100 - 10 = 90%

90% = 6 kg

1 % = 6/90

100% = 6/90 x 100 = 6.67 kg

Answer: 20kg of fresh mango is equivalent to 6.67 kg of dried mango
