Question

if fish cost 164and chips cost 134 and you went into the shop and asked for 2 fish and chips what would you be expecting to pay?​

Answer 1

Answer:

164+134 294 divide by 2 149 pay

Answer 2

Let there be x rupees needed for fish , y for monkey and z for lion .

So according to conditions

40x+y+z=100

And

x+3y+5z = 100.

Now we have 3 unknown and 2 equation so we have to find solution by trial and error. We also know that x cannot be greater than 2 as than there will be 120 fish . so assuming x to be 2 we get y as 1 and z as 19 . So one possible solution is 80 fish , 1 monkey and 19 lions.
