Question

The amount of water used for washing hands in three days is given below. Select the stage at which the conversion error is made.
(Hint: 1 gallon = 4 quarts)

	Day 1	Day 2	Day 3
Amount (gallon)	22	26	30
Amount (quarts)	88	105	130

• A. Day 2 and Day 3
• B. Day 1
• C. Day 2
• D. Day 3

Answer 1

The correct option is A Day 2 and Day 3

Day 1 quantity = 22 gallons
Day 2 quantity = 26 gallons
Day 3 quantity = 30 gallons

• 1 gallon = 4 quarts
• To get the volume in quarts, multiply 22 gallons with 4, as 1 gallon is equal to 4 quarts.
• For day $1:22\times 4=88$ quarts Thus, there are 88 quarts in 22 gallons.
• To get the volume in quarts, multiply 26 gallons with 4, as 1 gallon is equal to 4 quarts.
• For day $2:26\times 4=104$ quarts Thus, there are 104 quarts in 26 gallons.
• To get the volume in quarts, multiply 30 gallons with 4, as 1 gallon is equal to 4 quarts.
• For day $3:30\times 4=120$ quarts Thus, there are 120 quarts in 30 gallons.
• But the shown amount for day 2 and 3 in the table is 105 and 130 quarts.

Hence, day 2 and day 3 have the error in the conversion.
