# of boys is directly related to amount of ration and indirectly
related to amount of time.

b = k*r/t

Solve for "k" using "200 kg of ration lasts 3 months for 4 boys".
4 = k*200/3
k = 12/200 = 0.06
======================
Equation:
b = 0.06*r/t
----
how many boys will consume 650 of the ration in the same period?
b = 0.06*650/3
b = 13 (# of boys needed)
