Question

Si: m/ 25 = n/ 40 = p /50 = q/ 15 y, además: m – n + p = 63, hallar "n + q".

Answer 1

m/25=n/40  =  40/2m5 =n  = 8/5m= n
m/25=p/50 = 2m=p
m/25=q/15 =  15/25m =q = 3/5m=q

por lo tanto m-n+p=63
m-8/5m + 2m =63
m= 45

n= 72
p=90
q=27
 n+q=99

Answer 2

Si le quitamos 5 ta. a los denominadores nos queda así:
m/5 = n/8 = p/10 = q/3 = K
m = 5K , n = 8K , p = 10 K , q = 3K
Entonces:
m - n + p = 63
5K - 8K + 10K = 63
7K = 63
K = 9
Luego: n + q = 8K + 3K = 11K
11 (9) = 99
