Colin and Dan win some money and share it in the ratio 4:5. Colin gets £52. How much did they win in total?
1 answer:
Answer:
They won £117 in total.
Step-by-step explanation:
There are two methods to solve the question.
- Finding the total amount directly
- Finding Dan's share and adding it to Colin's share
It is given that the ratio is 4:5
Let x be the share of Dan
The ratio between Colin and Dan's share will be 52/x and it should simplify to 4/5
The total amount will be:
Hence,
They won £117 in total.

Without any calculations it's evident it can't be neither B (both numbers are even, so they're divisible by 2) nor C (the numbers end in 0 and 5, so they're divisible by 5).
A.
Both numbers have a factor of 3, so they're not relatively prime.
That means it must be D. But, let's check it.
Indeed, those two numbers are relatively prime.
