Correct Answer - Option 2 : 780
Given:
The ratio of prices of A and B = 6 ∶ 11
The ratio of prices of C and D = 30 ∶ 17
The price of C = 1600 + the price of B
The price of D = 1717
Formula:
If the ratio of A and B is a ∶ b, assume A = ak and B = bk where k is a constant.
Calculation:
Let the price of A and B be 6x and 11x respectively.
The price of C = 11x + 1600
The ratio of C and D = 30/17
⇒ (11x + 1600)/(1717) = 30/17
⇒ x = 130
The price of A = 6x
⇒ 6 × 130 = 780
∴ The price of A is 780.
