Answer 1

Answer:

1. a) 90, 120

2. d) 75

Step-by-step explanation:

1. let the two numbers be 3x and 4x

Sum = 3x + 4x = 210

7x = 210

x = 30

Numbers are 3x = 3×30 = 90

4x = 4×30 = 120

2. let the number be x

ATQ,

4x/5 = 10 + 2x/3

4x/5 - 2x/3 = 10

2x = 150

x = 75

the number is 75

Thanks!!!!

Answer 2

Your answer is : 90,120

Step-by-step explanation:

Let the no. be x

i.e. 3x and 4x

ATQ: 3x+4x=210

i.s 7x =210

x= 210/7

= 30

Therefore... 3x= 3*30=90

& 4x = 4*30 =120

Hope it helped you dear...
