Answer:

The sum of money put at SI was rupees 12,000

Step-by-step explanation:

SI (1) = PRT/100

= 4PR/100

= PR/25 rupees

Now,

3% higher rate = R + 3

P is the same

T is the same

=> SI (2) = 4P(R + 3)/100

= (PR + 3P)/25 rupees

According to the question,

SI (2) = SI (1) + 1440

=> (PR + 3P)/25 = PR/25 + 1440

=> (PR + 3P) /25 - PR/25 = 1440

=> 3P/25 = 1440

=> 3P = 36000

=> P = 12,000

Hence,

The sum of money put at simple interest was rupees 12,000
