Before solving it algebraically, let us prime factorize 1430 = 2*5*11*13.

Since number of apples per person * total persons = 1430, the answer should be a factor of 1430. Only C is. And that's your answer.

A. 20.
B. 21.
C. 22.
D. 23.
E. 24.

Since I didn't know what equation to make, I used the answer choices.

First I wanted to see if 1430 is divisible by anyone of the answer choices. (If non of the answer choices divided the number 1430, I would have simply guessed and moved to another question in actual test.)

A.1430/20 = 143/2
B 1430/21 = 1430/21
C 1430/22 = 65 (I checked this number first.)

If 1430 apple was divided among 65 people, each would have received 22. After addition of 45 people the answer should be 13. 1430/110 = 13.

Hi.
x*y = 1430
(x+45)*(y-9) = 1430
Solve the equation you get the answer

Hi please tell me what is wrong with this approach

let a -> average ( initial )
and n -> number of people ( initial)

(1430) / n - (1430)/ (n+45) = 9

but by solving i am getting very bad value of n.

kindly help

Your equation is correct and if you plug it into google you will get that n = 65.
Then you would need to divide 1430 by 65 to get answer (C).
But - this is an extremely complex quadratic equation.
If, like on this question, you find yourself in front of such a complex quadratic equation there is a very good chance that you've missed a shortcut. Look for it!
For example, look at the solutions using prime factorization above.
