Option 1 : 100000

**Given:**

Saloni and Khushi had to raise Rs. 300000 in 18 months with the help of Asha, they raised it in 15 months.

**Formula:**

Ratio of Profit = Ratios of product of Amount invested and time

Calculation:

Let the amounts invested by Saloni and Khushi be x and x + 60000 respectively.

According to the question,

x × 15 + (x + 60000) ×15 + 60000 × 10 = 300000 × 15

⇒ 15x + 15x + 900000 + 600000 = 4500000

30x = 3000000

x = 100000

∴ Amount invested by Saloni in the starting is Rs. 100000
