Correct Answer - Option 3 : 48000
Given:
Two partners X and Y invested a total of Rs. 88000 in their business for 3 months. Y then, decreased his amount by half for the next 9 months. X invested 9000 more in the next 9 months. The ratio of their profit is 187/120.
Formula:
Ratio of Profit = ratios of product of Amount invested and time
Calculation:
X : y
(88000 - x) : x
ATQ,
(88000 – x) × 3 + (88000 – x + 9000) × 9/ (3x + x/2 × 9) = 187/120
264000 – 3x + 873000 – 9x/ 7.5x = 187/120
136440000 – 1440x = 1402.5x
136440000 = 2842.5x
x = 48000
