Puneet and Malti ventured into a business with Rittu. Puneet's initial investment is 20% less than Malti's. The ratio of Puneet's initial investment to Rittu's is 8:5. After 'm' months from the business's commencement, Rittu withdrew from the venture. At the end of '6m' months, the total profit amounted to Rs. 47,200. Determine the value of 'm'.

ATQ, The ratio between the initial investments of Puneet and Raghav is 8:5 respectively. Let’s assume the initial investments of Puneet and Raghav is 8p and 5p respectively. The initial investment of Puneet is 20% less than the initial investment of Malti. 8p = (100-20)% of initial investment of Malti 8p = 80% of initial investment of Malti initial investment of Malti = 10p After ‘m’ months of the start of business, Rittu left it. Ratio among the investments  of Puneet, Malti and Rittu with respect to the time = 8p×m+8p×2m : 10p×m+10p×2m : 5p×m = 8+16 : 10+20 : 5 = 24 : 30 : 5 Here we cannot get the value of ‘m’ from the given information. So the answer cannot be determined
