A started a business with 25000 and B joined afterward with 30000. If the profit at the end of a year was divided in the ratio 5 : 2 respectively, then after how much time B would have joined A?
Answer & explanation
Correct answer: option 4
A B
inv.→ 25000 30000
× 12 × X
profit→ -----------------------------------------
given→ (5 : 2)
\(\frac{25000 × 12 }{30000× X }\) = \(\frac{5}{2}\)
\(\frac{25 × 12}{30X}\) = \(\frac{5}{2}\)
x = 4
So, B joined after ( 12 - 4 ) = 8 Months
