A.2 : 1

B.1 : 2

C.4 : 3

D.1 : 1

Answer & Explanation

Answer: Option C

Explanation:**5% of A + 4% of B = 2/3(6% of A + 8% of B)**

5A/100 + 4B/100 = 2/3(6A/100+8B/100)

⇒5A + 4B = 2/3(6A + 8B)

⇒15A + 12B = 12A + 16B

⇒ 3A = 4B

⇒ AB = 4/3

⇒ A:B=4:3

5A/100 + 4B/100 = 2/3(6A/100+8B/100)

⇒5A + 4B = 2/3(6A + 8B)

⇒15A + 12B = 12A + 16B

⇒ 3A = 4B

⇒ AB = 4/3

⇒ A:B=4:3
