If a/3 = b/2 then value of is 2a+3b/3a-2b is?
- 12/5
- 10/7
- 11/6
- None of these
Explanation
Given:
a/3 = b/2
Cross-multiply:
2a = 3b → a = (3b)/2
Now plug this value of a into the expression:
(2a + 3b) / (3a - 2b)
= [2(3b/2) + 3b] / [3(3b/2) - 2b]
= (3b + 3b) / (9b/2 - 2b)
= 6b / [(9b - 4b)/2]
= 6b / (5b/2)
= 6b × (2/5b) = 12/5
