B) 3 months |
Let investment of Amit = 12x
And investment of Brijesh = 11x
Let Bijesh invested the money for Y months.
Then
Amit's investment : Brijesh's investment
= (12x X 11) : (11x X y) = 132x : 11xy
= 12 : y
So \( \Large \frac{12}{y} = \frac{4}{1} \) [so ratio of profit is 4 : 1]
= > 4y = 12
So y = \( \Large \frac{12}{4} \) = 3 months
Hence, Brijesh invested money for 3 months.
