Correct Answer - Option 2 : 33
Calculation:
Let Aron has x pencils
⇒ Aditya has 2x pencils
⇒ Cost of pencils be p
⇒ Cost of x pencils = xp
⇒ Cost of 2x pencils = 2xp
⇒ 2xp - xp = xp
⇒ Aron has y sharpner
⇒ Cost of y sharpners = y(p + 2)
⇒ Aditya has y - 10 sharpner
⇒ Cost of Aditya's sharpner = (y - 10)(p + 2)
⇒ y(p + 2) -(y - 10)(p + 2) = 10(p + 2)
According to questions
⇒ xp = 10(p + 2)
⇒ (x - 10)p = 20
⇒ Minimum value of x = 11
∴ Total pencils = 3x
∴ Minimum value of pencils bought by Aron and Aditya together is is 3 × 11 = 33
