'Q' joined the business investing Rs. 6,000 more than 'P'. At the end of 25 months since 'P' started the business, ratio of profit share of 'P' to 'Q' was 5:4. Find the value of 'n'.Solution
Ratio of profit share of 'P' to 'Q'
= (9,000 × 25) : (15,000 × (25 − n))
= 15 : (25 − n) So,
15 : (25 − n) = 5 : 4 Or,
15 × 4 = 5 × (25 − n) Or,
60 = 125 − 5n Or,
5n = 65 Or,
n = 13
