In an ensemble of gongs, all gongs have a diameter of either ten inches, or twelve inches or fifteen inches. In the collection t

patriot [66]

Answer: Option 'E' is correct.

Step-by-step explanation:

Since we have given that

Let the total number of gongs be 'g'.

Number of ten inch gongs = 18

Let the number of 12 inch gongs be 'x'.

Let the number of 15 inch gongs be 'y'.

so, equation would be

$18+x+y=g$

Half of the gongs are tiger gongs is given by

$t=\dfrac{g}{2}\\\\g=2t$

Half of the 12 inch gongs are not tiger gongs

so, number of tiger gongs which is of 12 inch = $\dfrac{x}{2}$

Among the tiger gongs, there are equal numbers of ten inch, twelve inch and fifteen inch.

$\dfrac{x}{2}+\dfrac{x}{2}+\dfrac{x}{2}=t\\\\\dfrac{3x}{2}=t$

Half of the gongs are of 15 inch is given by

$y=\dfrac{g}{2}\\\\2y=g$

Since we have

$g=2t\\\\g=2\times \dfrac{3x}{2}\\\\g=3x\\\\\dfrac{g}{3}=x$

so, According to question, it becomes,

$18+\dfrac{g}{2}+\dfrac{g}{3}=g\\\\18+\dfrac{5g}{6}=g\\\\18=g-\dfrac{5g}{6}\\\\18=\dfrac{6g-5g}{6}=\dfrac{g}{6}\\\\18\times 6=g\\\\108=g$

Hence, Option 'e' is correct.
