let one no. b x

so th no.s r 15,45

Let one no. is x
2nd no. is 3x
by adding 15,
1st no. x+15
2nd no. 3x+15
Acc to condition,
2(x+15)=3x+15
2x+30=3x+15
3x-2x=30-15
x=15
3x=3(15)=45
The no. are 15 & 45
2nd no. is 3x
by adding 15,
1st no. x+15
2nd no. 3x+15
Acc to condition,
2(x+15)=3x+15
2x+30=3x+15
3x-2x=30-15
x=15
3x=3(15)=45
The no. are 15 & 45
