Answer:

376

Explanation:

800*7*2/100+700*16*2/100+500*4*2/100

112+224+40

Answer 2

Simple Interest

There are 3 cases given with different principal, different rate of inteest and same time period of 2 years.

We know that,

$Simple\ interest=\frac{principal\times\ rate \ of \ interest\times time\ period}{100}$

So, for CASE 1,

$S.I= \frac{800\times 7\times 2}{100}=112$

CASE 2,

$S.I= \frac{700\times 6\times 2}{100}=84$

CASE 3,

$S.I= \frac{500\times 4\times 2}{100}=40$

Henec total simple interest is $(112+84+40)=236$

So, required answer is rupees 236.
