Question

Solve this quick. Lets see who is good at math.

Mr. X has to cover a certain distance . he covers 2/5th of the total distance by car , 3/10th by bus, 1/5th by auto-rickshaw and the remaining 5 km on foot . What is the total distance?

Answer 1

And the answer is 50km

(2/5)+(3/10)+(1/5) = (9/10)

so remaining part is (1/10) which is equal to 5km

so net distance = 5x10= 50km

Answer 2

since 2/5ths converts into 4/10ths, the distance traveled by bus and care is 7/ths of the total distance.  Add another 2 tenths (converted from the auto rickshaw) and we are at 9/10ths the total distance making the remaining 5 km 1/10 of the total distance.  To find the total you simply multiply 5 by 10 making the total distance 50 km
