Balu’s investment = 1/2 * Raj’s investment Balu’s investment: Raj’s investment = 1: 2 Profit ratio = (4200 * 12): (8400 * 4): (X * certain months) Possible months = 1, 2, 3, 4, 5, 6, 7 From Option A => (4200 * 12)/(8400 * certain months) = 6 months This option satisfies the given condition. From Option B => (4200 * 12)/(5600* certain months) = 9 months This option does not satisfy the given condition. From Option C => (4200 * 12)/(4800* certain months) = 10.5 months This option does not satisfy the given condition. From Option D => (4200 * 12)/(3600* certain months) = 14 months This option does not satisfy the given condition.
