Step-by-step explanation:
The ratio of two numbers is 7:10 and their difference is 105. What are the numbers?
Don’t use pen or paper to solve these types of questions as you’ll waste more time and energy. I’m doing the following thing mentally to come up with answer in 5 seconds.
The difference between numbers is 105 ——(1)
The difference between ratio of numbers is 10–7=3 ——(2)
Divide (1) by (2)
105/3 = 35
Multiply both terms of the ratio by 35 to get the numbers
35*7/35*10 = 245/350
The numbers are 245 and 350
If you find it difficult to find 35*7 then find 35* (10–3) = 35*10 - 35*3 = 350- 105 =245
