Question
‘M’ invested Rs. 36000 in a business. ‘N’ joined
after ‘x’ months with an investment of Rs. 12000 less than ‘M’. If the ratio of the profits received by them after 2 years is 6:1, then find the time after which ‘N’ joined.Solution
Respective ratio of the profits received by ‘M’ and ‘N’
= (36000 × 24) : {24000 × (24 – x)} = 6/1
Or, 24 – x = 4
Or, x = 20 months
