Water in vegetables

Tomatoes in the store contain 99% water. After being transported to the shop, they were slightly dried and contained only 98% of water. How many kgs of tomatoes are in the store if there were 300 kg in stock?`

Result

x =  150 kg

Solution:

S=(1−0.99)⋅ 300=3 kg S=(1−0.98)⋅ x  x=S/(1−0.98)=3/(1−0.98)=150 kgS=(1-0.99) \cdot \ 300=3 \ \text{kg} \ \\ S=(1-0.98) \cdot \ x \ \\ \ \\ x=S /(1-0.98)=3 /(1-0.98)=150 \ \text{kg}
