In two triangle, the ratio of the areas is 4:3 and that of their heights is 3:4 the ratio of their bases is Choices
A) 16 : 9	B) 9 : 16	C) 9 : 12	D) 16 : 12	E) 4 : 12

Rationale: explanation : given a 1 / a 2 = 4 / 3 , h 1 / h 2 = 3 / 4 also , we know that a 1 / a 2 = ( 1 / 2 × b 1 × h 1 ) / ( 1 / 2 × b 2 × h 2 ) on substituting in above equation , we get b 1 / b 2 = 16 / 9 therefore b 1 : b 2 = 16 : 9 answer : option a
Answer: A
