The cost of renting a small bus for a trip was Taka X which was to be shared equally by 16 persons. Actually 10 person availed the trip. How much more Taka will be the cost per person?
সমাধান
সঠিক উত্তর: Option E
At first,
16 persons = X taka
1 person = X / 16 taka
Afterward,
10 persons = X taka
1 person = X / 10 taka
Now,
The difference would be:
(X/10) - (X/16) = (8X - 5X) / 80
= 3X / 80
