Problem 15. 10 dinar is divided equally among a group of men so that when 6 more men are added to their number and 40 dinar is divided equally among them, then each receives as much as he did previously. Find the original number of men.

2 men

Step-by-step explanation:

Initially, there were 'n' men and when 10 dinar were divided between them, each man got 'x' dinar. Then, there were 'n+6' men and when 40 dinar were divided between them, each man still got 'x' dinar. Modeling this system of equations gives us:

Solving for 'n':

The original number of men is 2.

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
