Answer 2

Given: Ratio of investment made by Jeff and Elon = 4:7

           The investment made by Bill is the same as that made by Elon

            Profit made at the end of the year = 20% = Rs. 75200

To Find: Amount invested by Bill

Solution:

• We can solve this question by using the following mathematical process:

• Let Investment made by Jeff be 4x

and let Investment made by Elon be 7x

According to the question,

             The investment made by Bill = 7x          (same as that made by Elon)

Total investment made = 4x + 7x + 7x = 18x

• Now profit made = 20 % of 18x

              ⇒ 20% of 18x + 18x = 75200

              ⇒ $\frac{20}{100}$(18x) + 18x = 75200

              ⇒ 18x($\frac{1}{5}$ + 1) = 75200

             ⇒ 18x × $\frac{6}{5}$ = 75200

             ⇒ x = 75200 × $\frac{5}{108}$

             ⇒ x = 3481.48

• Amount invested by Bill =7x

  So, 7x = 3481.48 × 7 = 24370.37

Therefore, the amount invested by Bill is Rs 24370.37.
