Question:

P : Q = 4 : 5 and R is 15% less than Q. If Q = 300, then what is the sum of P and R?

Options:

515

485

495

475

Correct Answer:

495

Explanation:

Here,

P : Q = 4 : 5 and R is 15% less than Q

⇒ Q : R = 100 : 85 = 20 : 17

P : Q : R

4 : 5

: 20 : 17

16 : 20 : 17

⇒ 20 units = 300

⇒ 1 unit = 15

⇒ P + R = 16 + 17 = 33 x 15 = 495
