Funny how we're not asked to find "X". grin
Anyway, OP, if you really wanted to know how many people went to the Cinema, you would take a cab, go to the Cinema house, and ask the person that sold the tickets on that fateful day.

The 120naira they paid at the cinema is subjective. It is a free will donation. Disregard the amount the men, women and children paid in the second sentence. The first sentence answers your question. 120 men, women and children made the donation. Thanks

[s]16 Men, 10 Women and 100 children!

16xN5 = N80
10xN2 = N20
100xN0.20 = N20

N80+N20+N20 = N120

There's your answer!
[/s]

Got the answer this time:
14 Men, 16 Women and 90 Children

Total people
14+16+90 = 120

Total amount in Naira (N)
(14xN5)+ (16xN2)+(90xN0.2) = N120

How did u arrive at that? Which formular did u use?
Note the number of male, female n children wen multiplied with the amount paid respectively must be equalled to 120naira.
Re: Brain Teaser. Test Your. Mathematical Skill by 2muchopoTBdope(m): 12:59am On Nov 15, 2014
op, u need three equations to find three unknowns and we only hv two,possibly, d question isn't complete.
x + y + z = 120..........equation 1
5x + 2y + 0.2z= 120.......equation 2

There are 3 unknowns for 2 equations.
You will have an infinite number of solutions.
