Question

A number
is divided into two parts
such that
part is 15 more than
the other. If the
two parts are in
the ration 7:4 find the number.​

Answer 1

Answer:

Since the two parts are in the ratio 5:3, then let the first number be 5x and second number be 3x. As second number is 10 more than the other, so it will be 3x+10.

5x=3x+10

2x=10

x=5

The first number becomes 5(5)=25 and second number becomes 3(5)=15.

The new number will be 25+15=40
