2 apples, 3 mangoes, 5 oranges = Rs 50 -------- (i)
5 apples, 8 mangoes, 14 oranges = Rs 140 --------(ii)
now, (ii) minus [(i)x2] => 1 apple, 1 mango, 2 mangoes, 4 oranges = Rs 40 -------- (iii)
if we subtract (iii) from (i) we get cost of 1 apple, 1 mango and 1 orange, which is Rs 10.

Why did we multiply (i) by 2?

2a+3m+5o=50 ----------eq1
5a+8m+14o=140---------eq2
(eq1)*3 - (eq1) = (a+m+o) = 50*3 - 140 = 10
So cost of 1 Apple + 1 Mango + 1 Orange is 10 Rupees
