3. Rs.18000
4. None of these
Answer : Option 2
Let their weighted ratio be 4x, 3x, and 4x
First of all, to calculate their weighted ratios
⇒ Shina =4 × 24 (2 years = 24 months) = 96
⇒ Bhuwan = 3 × 24 (2 years = 24 months) = 72
⇒ Preeti= 4 × 17 (24 months – 7 months) = 68
Ratio will be: 24:18:17
Total profit after 2 years = 14750 × 100/25 = Rs 59000
⇒ Investment by Preeti = 59000 × 17 / 59 = Rs 17000
Poonam, Swami & Deepa started a partnership business investing their money in the ratio of 3:5:7. After 3 months Kusum joined them and investing her money which is equal to the swami’s investment. Find the ratio of their profit at the end of the year.

2. 12:20:28:15
3. 12:20:28:25
4. None of these
Answer : Option 2
Let initial investment of Poonam, Swami & Deepa is 3x, 5x & 7x respectively, then Kusum’s investment is also 5x.
Like Poonam , Swami , Deepa invested for 12 months and Kusum invested for 9months.
Ratio of profit is equal to the product of their Investment & Time Period.
Therefore, Poonam: Swami : Deepa: Kusum = (3x*12):(5x*12):(7x*12):(5x*9)
= 12:20:28:15

Three partners Meena, Sheena and Love shared the profit in a partnership business in the ratio 3:4:7. They had partnered for 7 months, 7 months and 9 months respectively. Find their investment ratio?
1. 27:36:49
2. 29:37:49
3. 30:29:47
4. None of these
Answer : Option 1
Let their investments be Rs. x for 7 months, Rs. y for 7 months and Rs. z for 9 months respectively.
Then, 7x : 7y : 9z = 3:4:7.
Now, (7x/7y) = (3/4) ⇒ 4x= 3y ⇒ y = (4/3)x
And, (7x / 9z) = (3/7) ⇒ 49x = 27z ⇒ z = (49/27) x
By substituting the values of y and z in the form of x
Therefore, x : y : z = x : (4/3)x : (49/27)x
Hence, x:y:z = 27:36:49
Anu started a business with the amount of Rs. 27000 and after some months Kusum with the investing amount of Rs. 36000. At the end of year, the ratio of their profit is 3:2. After how many months Kusum joined?

Answer : Option 2
Suppose Kusum joined for x months. Then, (27000 × 12)/ (36000 × x) = 3/2.
By solving for x, we get the value of x = 6.
Hence, Kusum joined for 6 months.
