Answer:
The ratio of 2 numbers is 4:7. If 20 is added to the smaller number, then the number obtained is less than the greater number by 1. What are the 2 numbers and their sum?
solution:
As given that the ratio of two numbers= 4:7
So, let the required two numbers be 4x and 7x respectively where 4x> 7x.
a/q,
:. 4x + 20 = 7x-1
3x = 21
so, x = 7
thus, the two numbers are 28 and 49
and their sum = 28 + 49=77
