Answer & Solution
Correct Answer:
Option
A
Let initial expenditure = 100 units
Required increment = $$\frac{10}{90}$$ = $$\frac{1}{9}$$
1 unit = 10 apples
Original consumption = 9 units
= 9 × 10 = 90 apples
New consumption = 10 units
= 10 × 10 = 100 apples
New price = $$\frac{54}{100}$$ × 12 = Rs. 6.48 per dozen
Required increment = $$\frac{10}{90}$$ = $$\frac{1}{9}$$
1 unit = 10 apples
Original consumption = 9 units
= 9 × 10 = 90 apples
New consumption = 10 units
= 10 × 10 = 100 apples
New price = $$\frac{54}{100}$$ × 12 = Rs. 6.48 per dozen
