The family has Rs.350 in hand and they ate 3 Paratha and six Tikka and six Seekh kabab. Will they be able to manage to pay the bill within?​

Answer 1

Answer:

Can't afford

Step-by-step explanation:

Let prantha be p, tikka be t and seekh kabab be s then:

p + t + s = Rs. 150 (given).......i

2p + 2t + 4s = Rs. 200 (given).......ii

5p + 4t + 2s = Rs. 250 (given).......iii

ii - 2 x i we get:

s = 50

Now, p + t = Rs. 100.......v

5p + 4t = Rs. 150.....vi

vi - 5 x v we get:

t = 350

Now, p = -250

Family budget = -250 x 3 + 350 x 6 + 50 x 6 = -750 + 2100 + 300 = 2400 - 750 > 350
