An employee may claim Tk. 7 for each kilometer when he travels by taxi and Tk. 6 for each kilometer when he drives his own car. If in one week he claimed Tk. 900 for traveling 135 km, how many kilometers did he travel by taxi?
- A. 90 km
- B. 90 km
- C. 90 km
- D. 90 km
Answer: Option A
Explanation:
Let x and y be the respective km's travelled by man via taxi and by his own car.
Given x + y = 135 => x = 135- y
But according to the question,
7x + 6y = 900
7(135-y) + 6y = 900
=> 945 - 7y + 6y = 900
=> y = 945 - 900= 45
=> x = 135 - 45 = 90
Therefore, the distance travelled by taxi is 90 km.
Given x + y = 135 => x = 135- y
But according to the question,
7x + 6y = 900
7(135-y) + 6y = 900
=> 945 - 7y + 6y = 900
=> y = 945 - 900= 45
=> x = 135 - 45 = 90
Therefore, the distance travelled by taxi is 90 km.
