A started a business with 45000 and B joined afterward with 30000. If the profit at the end of a year was divided in the ratio 2:1 respectively, then B would have joined A for business after.
Answer & explanation
Correct answer: option 2
A B
inv.→ 45000 30000
× 12 × x
profit→ -----------------------------------------
given→ (2 1)
\(\frac{45000 × 12 }{30000×x }\) = \(\frac{2}{1}\)
\(\frac{18}{X}\) = \(\frac{2}{1}\)
x = 9
So, B joined after ( 12-9 ) = 3 Months
