Question

Sum of two no.Is 1000 and the difference between their squares is 256000. Find the no.

Answer 1

Answer:

Step-by-step explanation:

a+b=1000

a^2-b^2=256000

But (a+b)(a-b)=a^2-b^2

1000*(a-b)=256000

a-b=256000:1000

a-b=256 => a=256+b

256+b+b=1000

2b=1000-256

2b=744

b=744:2

b=372

a=372+256

a=628
