How you got 1435?

205*7 = 1435.

150/205 * 100 = 30/41 * 100.

0.7317 * 100 = 73.17%.

I don't know where I am doing mistake but I am not getting 73.17 answer, although I got 30/41 but after this I am helpless can you help me please.

Harihar Dash said: (Apr 11, 2016)  
The answer worked out to 73.17% seems incorrect.

150/205 * 100 = 30/41 * 100.
=> 3000/41= 74.63%.

Please clarify the correctness !

@Harish.

In your calculation, how you got 1500? Explain me.

Sandesh said: (Jan 11, 2017)  
@Harihar.

How it is 3000/41 = 74.63?

It must be 73.17.

Why we have to multiply by 100%?

Aleena said: (Nov 8, 2019)  
We have to multiply by 100% because acc to the question it is asked what percent of the total sales branches.
