Answer 1

Answer:

120

Step-by-step explanation:

Let the no. be x.

15 % of x = 15*x/100

&

20 % of x = 20*x/100

Their sum is 126

35x/100 = 126

x = 360

⅓ of x will be 360/3 = 120.

Answer 2

Answer: 120

Step-by-step explanation:

Let the positive number be x.  

According to the question,  

= x×(15+20)%x×(15+20)% = 126

= x×35=126×100x×35=126×100

Therefore, x = x=1260035x=1260035 = 360  

So, one-third of the number = 36033603 = 120.
