If the expenditure on tyres is Rs. 10000, then the expenditure on paint is how much more (in Rs.) more than the expenditure on seat?

Wheel ⇒ 72°

Paint ⇒ 36°

Seat ⇒ 12°

∴ Difference between expenditures on painting

and seat

⇒ 36°–12° = 24°

72° ≡ Rs. 10000

$herefore 24^{circ}=$ Rs. $left(frac{10000}{72^{circ}} imes 24^{circ} ight)=$ Rs. $left(frac{10000}{3} ight)$

$=$ Rs. $3333.33$
