P : Q = 4 : 5 and R is 15% less than Q. If Q = 300, then what is the sum of P and R?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 495.
Given:
P : Q = 4 : 5 and R is 15% less than Q.
Calculations:
Let's assume that P = 4x and Q = 5x.
Therefore, R = Q - 0.15Q = 0.85Q = 0.85(300) = 255
So, P = 4x = 4(60) = 240
Therefore, the sum of P and R = 240 + 255 = 495
Hence, the sum of P and R is 495.
