Given:
- Simple interest rate for the first period: 14%
- Simple interest rate for the second period: unknown
- Time period for the first period: 6.5 years
- Time period for the second period: 4.3 years
- Difference in interest for the two periods: Rs. 5000

To find:
- The sum of money lent by Mr Pappu Hatela

Solution:

Let's assume the sum of money lent by Mr Pappu Hatela is 'P' (in Rs).

Calculating interest for the first period:
- Rate of interest: 14%
- Time period: 6.5 years

Using the formula for simple interest:
Interest for the first period = (P * 14 * 6.5) / 100

Calculating interest for the second period:
- Rate of interest: unknown
- Time period: 4.3 years

Using the formula for simple interest:
Interest for the second period = (P * R * 4.3) / 100

Given:
Difference in interest for the two periods = Rs. 5000

Therefore, we can write the equation:
Interest for the first period - Interest for the second period = 5000

Substituting the values:
(P * 14 * 6.5) / 100 - (P * R * 4.3) / 100 = 5000

Simplifying the equation:
91P - 4.3PR = 500000

Calculating the sum of money:
To find the value of 'P', we need to solve the above equation.

Visually appealing solution:
Step 1: Calculate interest for the first period
Interest for the first period = (P * 14 * 6.5) / 100

Step 2: Calculate interest for the second period
Interest for the second period = (P * R * 4.3) / 100

Step 3: Formulate the equation for the difference in interest
Interest for the first period - Interest for the second period = 5000

Step 4: Simplify the equation
91P - 4.3PR = 500000

Step 5: Calculate the sum of money
Solve the equation to find the value of 'P'.
