Find the simple interest and the total amount after three years
Principal = 11.750 rupees
Annual rate of interest = 7.50
Total interest=
rupees
Total amount =
rupees

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

Add the cents that add the left overs to get the first number
