Question

1000 gallons of oxygen is required for space travel. Samuel carries 200 gallons of oxygen. Debora carries two times the gallons of oxygen carried by Samuel. Find the remaining gallons of oxygen to be carried.

• A. 400
• B. 600
• C. 200
• D. 800

Answer 1

The correct option is A 400

Total oxygen required = 1000 gallons

Gallons carried by Samuel (S) = 200

Gallons carried by Debora (D) = 2 x S $i.e.2\times 200=400$

Total gallons carried = S + D = 600 gallons

Remaining gallons to be carried =


The remaining amount of oxygen required to be carried for the space travel is 400 gallons.
