Question

2/3 part of my sum is lent out at 3% per annum, 1/6 part is lent out at 6% per annum and the remaining part is lent out at 12% per annum. All three parts are lent out at simple interest. If the annual interest income is ₹25, what is the sum?​

Answer 1

Answer:

RS.500

Step-by-step explanation:

Let entire sum = P

According to the question

23P×3%+16P×6%+[1−(23+16)]P×12%

=> 2P3×3100+P6×6100+[1−4+16]12P100=25

=> 2P100+P100+2P100=25

=> 5P=2500, P=500
