After some time, all the three investors with their obtained profit moved to another city and invested money(profit gained) in a chit fund which provided 10% annual return for Sita , 12% annual return for Geeta and 13% annual return for Monika . Find the ratio of returns after a year from the point they all invested in chit fund.?

Option 1 : 160 : 192 : 195

Profit of Rs. 7050000 which need to be distributed among Sita, Geeta and Monika in ratio of = 24000 : 24000 : 22500 = 240 : 240 : 225

Profit of each investor in Rs. 7050000

⇒ Profit of Sita = 7050000 × 240/705 = 2400000

⇒ Profit of Geeta = 7050000 × 240/705 = 2400000

⇒ Profit of Monika = 7050000 × 225/705 = 2250000

Annual returns of all three investors when they invested in chit fund

10 % annual return for Sita, 12% annual return for Geeta and 13% annual return for Monika

⇒ Annual return of Sita = 10% of 2400000 = 240000

⇒ Annual return of Geeta = 12% of 2400000 = 288000

⇒ Annual return of Monika = 13% of 2250000 = 292500

∴ Required ratio = 2400 : 2880 : 2925 = 480 : 576 : 585 = 160 : 192 : 195
