Question

Tina makes 480 sandwiches
She only makes tuna sandwiches, beef sandwiches, ham sandwiches and cheese sandwiches

3/8 of the sandwiches are tuna
35% of the sandwiches are beef

The ratio of the number of ham sandwiches to the number of cheese sandwiches is 5 : 6

Work out the number of ham sandwiches that Tina makes

Answer 1

Answer:

3 / 8 ×480 + 35 /100× 480 + 5x + 6x = 480

180 + 24 × 7 + 11x = 480

180 + 168 + 11x = 480

348 + 11x = 480

11x = 480 - 348

= 132

x = 132 / 11

= 12

no of ham sandwiches = 5x

= 5 ×12

= 60

therefore , the no of ham sandwiches = 60
