Answer 1

Answer:

Pineapple price = Rs 7

Step-by-step explanation:

Let say Price of Each pineapple = Rs P  per Piece

then 6 pinnepale Price = 6P  Rs

2 Jack fruit price = 60 - 6P  Rs

Jack fruit Price = 30 - 3P  Rs per Piece

Number of Pineppale in Rs 56  =  56/P

number of Jack fruits in rs 36 = 36/(30 - 3P)  = 12/(10 - P)

56/P = 4 + 12/(10 -P)

=> 14/P  = 1 +  3/(10 - P)

=> 14(10 - P) = P(10-P)  + 3P

=> 140 - 14P = 10P - P² + 3P

=> P² - 27P + 140 = 0

=> P² - 7P - 20P + 140 = 0

=> P(P -7) -20(P - 7) = 0

=> P = 7   & P = 20

for P = 20 Jack fruit price become = - 30 Rs

so P = 20 not possible

Hence P = 7

Pineapple price = Rs 7
