Question
‘R’ invested Rs. 4000 in a business. ‘S’ joined
x months later with an investment of Rs. 3000. If at the end of the year, S’s share in the profit is Rs. 2250 out of a total profit of Rs. 6750, find the value of x.Solution
According to the question,
(4000 × 12) : {3000 × (12 – x)} = (6750 – 2250) / 2250
Or, 48000 : {3000(12 – x)} = 4500 / 2250
Or, 48000 : {3000(12 – x)} = 2 : 1
So, 48000 × 1 = 2 × 3000(12 – x)
48000 = 6000(12 – x)
48000 = 72000 – 6000x
6000x = 72000 – 48000
6000x = 24000
x = 4 months
