Q: If a : b : c = 2 : 3 : 7 then what will be the value of 2a : 3b : 7c
  • A. 6 : 10 : 49
  • B. 6 : 10 : 47
  • C. 4 : 9 : 49
  • D. 5 : 10 : 52
Correct Answer: Option C - According to the question, a : b : c = 2 : 3 : 7 a = 2 b = 3 c = 7 then 2a : 3b : 7c = 2×2 : 3×3 : 7×7 = 4 : 9 : 49
C. According to the question, a : b : c = 2 : 3 : 7 a = 2 b = 3 c = 7 then 2a : 3b : 7c = 2×2 : 3×3 : 7×7 = 4 : 9 : 49

Explanations:

According to the question, a : b : c = 2 : 3 : 7 a = 2 b = 3 c = 7 then 2a : 3b : 7c = 2×2 : 3×3 : 7×7 = 4 : 9 : 49
