          Principal   :    Installment

1st  ⇒     6        :           7

2nd ⇒    36         :         49                 

* Installment amount for each year should be same*

Therefore,

 

          Principal   :    Installment

1st  ⇒     6        :           7    ) × 7

2nd ⇒    36         :         49    ) × 1

 

          Principal   :    Installment

1st  ⇒    42         :          49

2nd ⇒    36        :           49   

 Sum ⇒   78      :         49 (Each Installment)

 

               49                    78

                ↓                      ↓

              ×15                   ×15

                ↓                      ↓

         735(given)             1170
