14.
A farmer travelled a distance of 61 km in 9 hours. He travelled partly on foot @ 4 km/hr and partly on bicycle @ 9 km/hr. The distance travelled on foot is:
Answer: Option
Explanation:
Let the distance travelled on foot be x km.
Then, distance travelled on bicycle = (61 -x) km.
| So, | x | + | (61 -x) | = 9 |
| 4 | 9 |
9x + 4(61 -x) = 9 x 36
5x = 80
x = 16 km.

Please someone tell why the answer is not coming by allegation? I used foot on left 4 9.
6.7.
2.3 2.7.
= 61*23/27?
Why can't we solve like this?

We can solve using avg method 2xy/x+y.
Let,
x=4.
y=9.
Then,
2(4)(9)/4+9=4.
Distance traveled on foot is 4 km/h.
So,
4*4=16.
Let,
x=4.
y=9.
Then,
2(4)(9)/4+9=4.
Distance traveled on foot is 4 km/h.
So,
4*4=16.

9 hours mean 9 times. So the procedure is;
4km, 9km,
4km, 9km,
4km, 9km,
4km, 9km.
So on foot, he travelled 16 km.
4km, 9km,
4km, 9km,
4km, 9km,
4km, 9km.
So on foot, he travelled 16 km.

Total distance D = 61
4km/hr for 4 hr = 16
9km/hr for 5 hr = 45
Adding 45+16=61.
Hence answer =16.
4km/hr for 4 hr = 16
9km/hr for 5 hr = 45
Adding 45+16=61.
Hence answer =16.

Partly means is it not (x/2 )/4+(x/2)/9=9 if d is taken as the total distance?
Please tell me.
Please tell me.

@Dhivagar.
What if I take 5 hr for bicycle and 4 hr for foot. The answer will be 20 right?

By Using alligation method.
4:5=9.
So, 4 * 4 = 16 by walking,
5*9 = 45 by cycle.
4:5=9.
So, 4 * 4 = 16 by walking,
5*9 = 45 by cycle.
