A started a business with 40000 and B joined afterward with 32000. If the profit at the end of a year was divided in the ratio 3:1 respectively, then after how much time B would have joined A?
Answer & explanation
Correct answer: option 3
A B
inv.→ 40000 32000
× 12 × X
profit→ -----------------------------------------
given→ (3 : 1)
\(\frac{40000 × 12 }{32000× X }\) = \(\frac{3}{1}\)
\(\frac{15}{X}\) = \(\frac{3}{1}\)
x = 5
So, B joined after ( 12 - 5 ) = 7 Months
