1.	If 20% of P = 30% of Q = 1/6 of R, then P: Q : R is equal to:1. 1 : 2 : 42. 5 : 10 : 63. 15 : 10 : 184. 2 : 5 : 8
Answer» Correct Answer - Option 3 : 15 : 10 : 18 Given: 20% of P = 30% of Q = 1/6 of R Calculation: Let 20/100 × P = 30/100 × Q = 1/6 × R = k ⇒ P/5 = 3Q/10 = R/6 = k ⇒ P = 5k ⇒ Q = 10k/3 ⇒ R = 6k ∴ P : Q : R = 5k : 10k/3 : 6k ⇒ 15k : 10k : 18k = 15 :10 : 18 ∴ The correct answer is 15 : 10 : 18

If 20% of P = 30% of Q = 1/6 of R, then P: Q : R is equal to:1. 1 : 2 : 42. 5 : 10 : 63. 15 : 10 : 184. 2 : 5 : 8

Answer» Correct Answer - Option 3 : 15 : 10 : 18

Given:

20% of P = 30% of Q = 1/6 of R

Calculation:

Let 20/100 × P = 30/100 × Q = 1/6 × R = k

⇒ P/5 = 3Q/10 = R/6 = k

⇒ P = 5k

⇒ Q = 10k/3

⇒ R = 6k

∴ P : Q : R = 5k : 10k/3 : 6k

⇒ 15k : 10k : 18k = 15 :10 : 18

∴ The correct answer is 15 : 10 : 18
