Answer:_______________

The sum of 1468 deposited in a bank gives an interest of 142 in 3 months.what will be the interest on 2079 for 6 months at the same rate of interest

Answer: 403.28

SOLUTION 1 :

Soln:

principal	No of interest	No of months
1468	142	3
2079		6

Step:1

Consider the principal & interest.As the principal increases from 1468 to 2079.The no of interest also increases.

It is in inverese variaton.

the multiplying factor = $\frac{2079}{1468}$

Step :2

Consider the principal & months.As the no of months increases from 3 to6.The no of interest increases.

It is in inverese variation.

The multiplying factor = $\frac{6}{3}$

x = $\frac{6}{3}$ x $\frac{2079}{1468}$ x 142

= 1.42 x 2.00 x 142

= 403.28
