Solution:

  • Total Blue = 1000
    • Blue Scented = 25% of 1000 = 250
    • Blue Un-Scented = 75% of 1000 = 750
  • Total Green = 1000
    • Green Scented = 250% of G = \(\frac{G}{2}\)
    • Green Un-Scented = 50% of G = \(\frac{G}{2}\)

  • We already know total Un-Scented = 1000
  • Or, \(750+\frac{G}{2}=1000\)
    \(⇒\frac{G}{2}=250\)
    \(⇒G=500\)
  • Total candies in the shop \(= 1000+G=1000+500=1500\)

  • Candies sold out = candies neither scented blue nor scented green = total uncented candles = 1000
  • So, number of candies left \(= 1500 - 1000 = 500\)\(\)

Hence the right answer is Option C
