Percy and Nelly Cod are brother and sister from a large family.
Percy was 19 pence short of the amount needed to buy a badge. Nelly, meanwhile, was just one penny short of affording the same type of badge. They decided to pool their money to buy one badge to share, but even together, they still didn’t have enough.
Here’s what we know about the Cod siblings:
Percy has three times as many sisters as brothers.
Nelly has twice as many sisters as brothers.
How much would it cost Mr and Mrs Cod (Nelly and Percy's parents) to buy badges for all of their children?
