Question

This week Bob puts gas in his truck when the tank was about half empty. Five days later, bob
puts gas again when the tank was about three fourths full. If Bob Bought 24 gallons of gas,
how many gallons does the tank hold?

Answer 1

Answer:

first the tank was half empty and then he puts some gas second time the tank was three- fourths full means in the first time he filled one- fourth of the tank and then he fills again.

so total half of the the tank is filled by Bob in both the times .

gallons bought by Bob = 24

but he filled only half

so gallons required to fill half the tank = 24

therefore tank's capacity = 48 gallons
