Question

los 3/5 de X% del 60% de los 2/7 de 35000 es 144. hallar x

Answer 1

X% = X/100

60% = 60/100 = 3/5

(3/5)(X/100)(60/100)(2/7)(35000) = 144

(3/5)(3/5)(2/7) = (9/25)(2/7) = (18/175)

(18/175)(X/100) = (18X/17500)

(18X/17500)(35000) = 144

[(18X)(35000)/(17500)] = 144

[(18X)(35000)/(17500)] = (36X) = 144

X = 144/36

X = 4

%X = 4/100 = 1/25

X = 4% 

Answer 2

(3/5)(X)%(60)%(2/7)(35000)=144
(3/5)(X/100)(60/100)(2/7)(35000)=144

(3)(X)(60)(2)(35000) ÷ (5)(100)(100)(7)   =   144

12600000 (X) ÷ (350000)  =  144

X= 350000 * 144 ÷ 12600000

X=4
