PLEASE ANSWER WITH SOLUTION PLS
katen-ka-za [31]

Answer:

whatever% of anything, is just (whatever/100) * anything.

there were a total of 560000 votes, now, off those some are valid and some are invalid.

we know 15% of that are invalid, that simply means that 85% are valid, since 85% + 15% is the whole thing, or 100%, if 15% are not good, the other 85% are the good ones.

how many are the valid ones anyway?  well, 85% of 560000, which is just (85/100) * 560000.

we know that off those valid ones, the candidate got 75% of those, so how much is 75% of that?

well, (75/100) * [ (85/100) * 560000 ].

Lera25 [3.4K]

Given:

The price of bananas can be determined by the equation P=0.25n, where P is the price and n is the number of bananas.

To find:

The constant of proportionality

Solution:

We have,

P=0.25n       ...(i)

where P is the price and n is the number of bananas.

Price P is directly proportional to the number of bananas. So,

P\propto n

P=kn            ...(ii)

Where, k is the constant of proportionality.

On comparing (i) and (ii), we get

k=0.25

Therefore, the constant of proportionality is 0.25.
