Correct Answer - Option 5 : Rs. 1900
Given∶
Ram invested 20% more than Raja.
Raja invested 20% less than Rana.
Total investment = Rs. 5244
Formula Used∶
Basic knowledge of addition, multiplication and division
Calculation∶
Let money invested by Rana = Rs x
Then, money invested by Raja = 4x/5 = 0.8x
Money invested by Ram = 4x/5 × 120/100 = 0.96x
Also, x + 0.8x + 0.96x = 5244
2.76x = 5244
x = 5244/2.76 = 1900
∴ Amount invested by Rana is Rs. 1900.
