pls solve 2 q pls I want this ​

Answer 1

Answer:

Correct option is

D

both a and b

⇒  The two numbers are a and b

According to the question,

⇒  a+b=15      

⇒  a=15−b    ---- ( 1 )

⇒  a1+b1=103

⇒  15−b1+b1=103

⇒  b(15−b)b+15−b=103

⇒  150=3b(15−b)

⇒  50=b(15−b)

⇒  50=15b−b2

⇒  b2−15b+50=0

⇒  b2−10b−5b+50=0

⇒  b(b−10)−5(b−10)=0

⇒  (b−10)(b−5)=0
