If R : S = 5 : 3 and R + S = 96 , then the value of 3(R - S) : (R + S) is?
Answer & explanation
Correct answer: option 3
R : S = 5 : 3
3(R - S) : (R + S) = 3(5 - 3) : (5 + 3) = (3 × 2) : 8 = 6 : 8 = 3 : 4
If R : S = 5 : 3 and R + S = 96 , then the value of 3(R - S) : (R + S) is?
Correct answer: option 3
R : S = 5 : 3
3(R - S) : (R + S) = 3(5 - 3) : (5 + 3) = (3 × 2) : 8 = 6 : 8 = 3 : 4
