Direction: Study the information given below and answer the question that follows.
There are 6 types of mirror in a shop A, B, C, D, E and F. Information about their prices is given below:
i) The prices of A and E is the same.
ii) The ratio os prices of C and D is 7:6.
iii) The price of E is Rs. 25 less than that of B.
iv) The price of D is 4/3rd of that of F.
v) The price of C is Rs. 70
vi) The price of F is Rs. 5 less than that of E.
Show answer & explanation
From the given relations: C = 70. Since C/D = 7/6, D = 60. D = (4/3)F implies F = 45. F = E - 5 implies E = 50. A = E = 50. B = E + 25 = 75.
Step-by-step Derivation:
Step 1: From condition (v): Price of C = Rs. 70.
Step 2: From condition (ii): C : D = 7 : 6 => D = 70 * (6/7) = Rs. 60.
Step 3: From condition (iv): D = (4/3)F => F = 60 * (3/4) = Rs. 45.
Step 4: From condition (vi): F = E - 5 => E = 45 + 5 = Rs. 50.
Step 5: From condition (i): A = E = Rs. 50.
Step 6: From condition (iii): B = E + 25 = Rs. 75.
