Answer:_______________

The sum of 1062 deposited in a bank gives an interest of 149 in 4 months.what will be the interest on 2068 for 9 months at the same rate of interest

Answer: 653.74

SOLUTION 1 :

Soln:

principal	No of interest	No of months
1062	149	4
2068		9

Step:1

Consider the principal & interest.As the principal increases from 1062 to 2068.The no of interest also increases.

It is in inverese variaton.

the multiplying factor = $\frac{2068}{1062}$

Step :2

Consider the principal & months.As the no of months increases from 4 to9.The no of interest increases.

It is in inverese variation.

The multiplying factor = $\frac{9}{4}$

x = $\frac{9}{4}$ x $\frac{2068}{1062}$ x 149

= 1.95 x 2.25 x 149

= 653.74
