Question

Thank you 45% ful and contents 42 litres of water what is the full capacity of the tank also find how many litres of water must be added to make it 75% full

Answer 1

Answer:

The amount of water to be added is 28 litres

Step-by-step explanation:

Let V be the total volume of the tank

Given that:

45% of V = 42

0.45 * V = 42

V = 42 / 0.45

V = 93.33 litres

75% of V = 0.75*93.33

                = 70

Hence, we need a volume of 70 litres of water in the tank. Since it already contains 42 litres, the additional water needed will be:

70 - 42 = 28 litres

Answer 2

Answer:

the amount if water to be added is 28 liters

Step-by-step explanation:

ler V be the total volume of the tank

given that

45% of V=42

0.45 of V=42

0.45*V=42

V=42/0.45

V=93.33 lit

75% of V

0.75*93.33

=70 lit

Hence,we need volume of 70 lit of water in the tank,since it already contains 42 lit the additional water needed will be 70-42=28 lit
