# Easy Algebra Solved QuestionAptitude Discussion

 Q. Naveen purchased two oranges, 3 apples and 5 bananas and paid Rs 40. Had Naveen purchased 3 oranges, 5 apples and 9 bananas, He would have to pay Rs 64. Gagan demanded only 1 orange, 1 apple and 1 banana. If Naveen purchased only what was demanded by Gagan, then how much would he have paid (in Rs)?
 ✔ A. 16 ✖ B. 28 ✖ C. 36 ✖ D. 24

Solution:
Option(A) is correct

Let the cost of each orange, apple and banana be $o, a$ and $b$ respectively.
Given,

$2(o)+3a+5b=40$ -------- (i)

$3(o)+5a+9b=64$-------- (ii)

From 2(i) - (ii):

$⇒ o+a+b=16$

I would give u some easy guessing that in two of the purchases the difference is Rs.24/-, So for 24 rupees he got 1 orange, 2 apples, 4 bananas so clearly it should be less than Rs.24/-. So from the options it would be Rs. 16/-
